In a Facebook post, the CSIS on Tuesday said, “On this National Day of Remembrance for Victims of Terrorism, CSIS remembers the 329 people on Air India Flight 182 who lost their lives due to a heinous act of terror. On June 23, 1985, a bomb planted by Canada‑based Khalistani extremists destroyed the aircraft, killing everyone on board—most of them Canadians. It remains the deadliest terrorist attack in Canada’s history and a defining moment for our national security community.”
