Opening
Good morning, and welcome to The Shomer Brief. This is your security brief for Friday, November 13th, covering antisemitic attacks, assaults, and incidents worldwide over the previous 24 hours.
Bottom line up front
We tracked one verified new incident in this window. The most serious — and only — qualifying incident was in Giessen, Germany, where a synagogue was evacuated after an antisemitic threatening letter containing an unidentified powder was opened inside. No one was injured. The clearest pattern is timing: this threat arrived just days after Germany commemorated Kristallnacht, and it follows the same post-anniversary pattern seen in last week's brief. No verified new qualifying incidents were found in the United States, Canada, Israel and the Middle East, or elsewhere in this 24-hour window — reporting was thin, and feeds were largely resurfacing older stories, which are listed under Checked and excluded below rather than padded into the brief.
United States
No verified new qualifying incident in this window.
Canada
No verified new qualifying incident in this window. See Developments for an update on the Montreal restaurant series reported on November 12th, concerning an incident on November 11th.
Europe
- November 12, Giessen, Germany. At approximately 12:50 p.m., a synagogue in Giessen was evacuated after a threatening letter containing an unidentified powder was opened inside the building. According to Central Hesse police, 26 people were inside at the time and were evacuated as a precaution. Four people who were in the immediate vicinity of the letter were examined by paramedics; none suffered injuries, and all were released at the scene without further treatment. Police, firefighters, and emergency medical personnel responded. Authorities confirmed the letter contained antisemitic and threatening messages. The nature of the powder has not yet been determined, and no arrest has been reported. Giessen Mayor Frank-Tilo Becher condemned the incident as a deliberate attempt to intimidate the city's Jewish community, saying: "The sender wanted to say: Jewish people are not welcome here," and linking it to the city's commemoration, just days earlier, of the November 1938 Kristallnacht pogrom, during which synagogues in Giessen were destroyed. Status: investigation into the letter's origin and the powder is ongoing.
Israel / Middle East
No verified new qualifying incident in this window. Items from the region in this window concerned the Israel–Hamas conflict and an assault on a Christian nun in Jerusalem — neither is an attack against the Jewish population, so both are out of scope and are noted under Checked and excluded.
Israel — Red Alert summary (Home Front Command alert data)
One alert event sounded in this window.
- November 13, 2:56 a.m. Israel time, Nahal Oz, Gaza Envelope. Sirens sounded in the kibbutz of Nahal Oz, beside the Gaza Strip, in a rocket and missile fire alert that gave residents 15 seconds to reach shelter. The Home Front Command all-clear followed at 3:00 a.m. — the threat lasted about four minutes. The IDF examined the alert and concluded it was a false identification: no rocket was launched, and there were no interceptions, impacts, injuries, or damage. The alert dataset attributes alerts in this area to Hamas as a standing estimate, but the IDF's finding controls here — this was a false alarm, not an attack. No other alerts sounded anywhere in Israel during this 24-hour window; November 12th was a zero-alert day nationwide.
Other regions
No verified new qualifying incident in this window.
Developments
- November 12 reporting, Montreal, Canada — update on the November 11 Schnitzels attack. The Algemeiner, reporting November 12th, added new detail to the Schnitzels case covered in yesterday's brief: the Queen Mary Road restaurant was broken into and robbed on Wednesday, November 11th. Owner Joseph Cohen told the Montreal Gazette that $700 to $800 in cash, as well as personal receipts, were stolen. No arrests have been made. Cohen was quoted as devastated by the series against Jewish-owned businesses, while also saying he did not necessarily believe this break-in was directed antisemitism, and asking why his business, in a popular area for cafés, was hit. B'nai Brith Canada calls Schnitzels the third Jewish-owned business targeted in seven days, after Pizza Pita on November 9th and the Mimimelon bakery arsons on November 2nd and 4th. Police have not confirmed a hate motive or a link between the cases.
- November 10 sentencing, reported November 12, Toronto, Canada. A teenager, identified only as J.B. because he was 17 at the time, was sentenced on Tuesday, November 10th to two years in a custodial facility followed by one year of community supervision — the maximum permitted for these offences under Canada's Youth Criminal Justice Act — for shooting at two synagogues in March: Beth Avraham Yoseph in Vaughan shortly before midnight on March 6th, and Shaarei Shomayim in Toronto shortly after midnight on March 7th. No one was injured in the shootings. The Canadian Press report was first published November 12th. The court described the shootings as "planned, calculated and brazen." Jewish organizations, including the Friends of Simon Wiesenthal Center Canada, CIJA, and UJA Federation, welcomed the maximum sentence and are pressing the open question in the case: court records established the teenager was paid to carry out the shootings, and who paid him has not been identified.
- November 6 incident, arrest reported November 12, Lawrence, New York. The New York Post reported November 12th that Saul Amantecatl Sanchez, 26, of Brooklyn, was arrested on Tuesday and charged with first-degree aggravated harassment and making graffiti, after a swastika was found drawn on a door at the Marion and Aaron Gural Jewish Community Center in Lawrence, on Long Island, on November 6th. Police say Sanchez was on the premises making a delivery and allegedly drew the swastika with his finger on a door in the parking lot. The JCC said the incident did not appear to have been premeditated, and that the safety of its students, staff, and visitors remains its highest priority.
- November 12, Canada. B'nai Brith Canada issued a statement on November 12th saying the federal government's Advisory Council on Rights, Equality and Inclusion has been virtually invisible since its creation five months ago, and that B'nai Brith cannot get a meeting with it, while it says it has documented another 108 incidents of violence and vandalism targeting Canadian Jews since June. This is advocacy context for the Montreal and Toronto cases above, not a new incident.
Watch items
- Sunday, November 15, Philadelphia. Organizers of the November 8th "boycott ride" against six Jewish-owned restaurants near Rittenhouse Square have announced a follow-up "ride of return" for this Sunday, November 15th. The six businesses are Schlesinger's Deli, Dizengoff, Goldie, Huda, K'Far Café, and Mac Mart. Expect counter-support, as on November 8th, and a police presence. Institutions and businesses in that area should hold a heightened posture on Sunday.
- Giessen, Germany. Results on the identity of the powder in the November 12th letter, and any identification of the sender, are pending. A result showing a harmless substance would not change the threat finding — authorities are treating the letter itself as the antisemitic threat.
- Montreal, Canada. Police hate-crime and arson investigations into the Mimimelon, Pizza Pita, and Schnitzels series remain open with no arrests reported. Any fourth business hit would confirm a continuing local series.
Assessment
The threat posture remains elevated, even on a quiet day. One incident in 24 hours is a thinner day than the week covered yesterday, but the Giessen case matters in kind, not just count: a mailed threat with a powder, timed just after Kristallnacht commemorations, is designed to force an evacuation and to frighten a whole congregation at low cost and low risk to the sender. Paid-for-hire attacks also remain a live concern — the Toronto sentencing leaves an unidentified payer behind two synagogue shootings, and that question is still unanswered. Recommendation: maintain heightened posture through the weekend, with particular attention to Philadelphia on Sunday, November 15th, and to mail-handling procedures at synagogues and community centers.
Checked and excluded
Note: several of the reports below are currently making the rounds on the internet and in news feeds again. Each one was checked against its actual date and shown to be an older report, or otherwise outside this brief's scope. They are listed here with the full date — including the year — that each actually occurred, so nothing is silently missed.
- Manchester, England synagogue attack (Jihad Al-Shamie) — excluded as stale. Resurfacing in feeds this morning; the attack took place on Yom Kippur, October 2, 2025, not in this window.
- Bondi Beach, Sydney Hanukkah shooting — excluded as stale / out of window. Feeds this morning recirculated reporting dated to the December 14th, 2025 Hanukkah event, not November 12–13, 2026.
- Melbourne, Australia, Adass Israel Synagogue arson — excluded as stale. The fire was on December 6th, 2024, in the original reporting recirculated this morning; not in this window.
- Brooklyn rabbi beaten (Eric Avrutov case), Brooklyn teen slashed in a synagogue, and the Manhattan Upper West Side stabbings — excluded as stale. Dates in the underlying reporting are September 25th, 2026, September 15th, 2026, and July 24th, 2026 respectively, despite resurfacing in November 12–13 feeds. The rabbi case was also reported by police as not being treated as a hate crime at this time.
- Williamsburg, Brooklyn assault, November 7–8, 2026 — excluded as out of window. Already covered in the November 12th brief.
- Geneva, Switzerland, "Death to the Jews" graffiti at a bus stop — excluded as out of window. Dated November 10th, 2026 in Combat Antisemitism Movement reporting published November 12th; not in the previous 24 hours.
- University of Michigan / Jewish Federation of Metropolitan Detroit indictment — excluded as stale development. A November 12th, 2026 republication recirculated the case; the original indictments were unsealed in June 2026, and the superseding indictment expanding the case to 12 defendants was unsealed October 30th, 2026. No new charge in this window was verified.
- Bridgeport, Connecticut, Congregation B'nai Israel vandalism statement — excluded as unverified for this window. The mayor's statement was published November 12th, 2026, but its own text says the crime took place "shortly after Hanukkah," and no date in this window could be verified for the vandalism itself, nor could its year be established from the statement.
- Jerusalem assault on a French nun — excluded as out of scope. Reported November 13th, 2026, concerning an attack on Tuesday in which a Jewish man was arrested for assaulting a Christian nun. The victim was not Jewish and the attack was not directed at the Jewish population, so it does not meet this brief's scope.
- Nasser Hospital, Khan Younis strike, November 12, 2026 — excluded as out of scope. Six people were reported killed in Gaza on November 12th, 2026 in the Israel–Hamas conflict. That is general conflict reporting, not an antisemitic attack against the Jewish population, per the scope set for this brief.
- Charlotte, North Carolina school and Shalom Park items — excluded as out of window. The Charlotte Country Day swastika video reporting is dated November 7–11, 2026, and the Shalom Park hate-crime guilty plea on November 10th, 2026 concerns a January 19th, 2026 incident. Neither is a new incident in this window.
