President Donald Trump said a ceasefire between Iran and Israel was “in effect” on Tuesday, after expressing deep frustration with both sides for violating the agreement he brokered.

But in the hours before the ceasefire took effect early in the morning, Israel said it had killed “hundreds” of Iranian security personnel in bombing raids in Tehran, while an Iranian missile pierced Israeli air defences, hitting a residential building in Beersheba, killing at least four people.
