Iran’s Islamic Revolutionary Guard Corps (IRGC) say that Hamas’s political leader, Ismail Haniyeh, was killed by “a short-range projectile with a warhead of about 7 kilograms accompanied by a severe explosion from outside his room”, Al Jazeera reports.

In a statement, the IRGC said his assassination had been “planned and carried out by the Zionist regime” and supported by the “criminal government of the US”.

It says Tehran’s response will be “severe and at the appropriate time, place and manner”.
