Following three attacks on synagogues in Toronto last month, the US has seen at least four terrorist attacks in the last three weeks: a Senegalese supporter of Iran shot nightclubbers in Austin, Texas; ISIS terrorists threw three bombs which failed to detonate in New York City at a crowd of anti-Islam protestors; a Hezbollah family member attacked Michigan’s oldest Jewish community with firearms and explosives which he failed to detonate and a man shouting “Allahu akbar” attempted to murder an ROTC class at Virginia’s Old Dominion university, killing one.

Two synagogues/Jewish schools in Rotterdam and Amsterdam and one in Liege, Belgium, were the subject of unsuccessful bombings.

In the UK around 10 suspected Iranian spies were arrested for spying on Jews in London.

Two of the American attacks came after the Trump administration leaked to journalists counter-intelligence indicating Iran had sent a “go signal” to “sleeper cells” in North America. Security was increased in Los Angeles for the Academy Awards over the weekend.
