Officers looking into attacks on Iran International media offices, synagogue and Jewish charity ambulances

Counter-terrorism investigators are examining three separate arson attacks in London against an Iranian dissident and Jewish targets amid fears the Iranian state may be behind them.

The latest attack happened at about 8.30pm on Wednesday, outside the offices of Iran International, a Persian-language news channel that opposes the regime in Tehran.

The Metropolitan police said an “ignited container” had been thrown at a car park at the company’s offices in Wembley. The fire immediately went out. After a police pursuit involving an armed response vehicle, a 16-year-old boy and two men, aged 19 and 21, were arrested on suspicion of arson endangering life.

It followed an attempted firebomb attack on Finchley Reform Synagogue on Wednesday morning, and an arson attack last month on four ambulances in Golders Green run by a Jewish charity.
