Richard Moore, the head of Britain’s MI6 foreign intelligence agency, has said he believes that Iran is still planning to respond to the killing of Hamas leader Ismail Haniyeh, which Tehran blames on Israel, Al Jazeera reports.

“I suspect they will try and we won’t be able to let our guard down for the type of activity that the Iranians might try and prosecute in that direction,” Al Jazeera quoted Moore as saying at an event in London.

Haniyeh’s assassination provoked anger across Palestine and stoked fears about a wider regional conflict amid Israel’s offensive on Gaza.
