The Israeli military said it struck Hezbollah’s headquarters in Beirut on Friday late-night in a series of massive explosions that targeted the leader of the militant group and levelled multiple high-rise apartment buildings.

At least six people were killed and 91 were wounded, Lebanon’s health ministry said. It was the biggest blast to hit the Lebanese capital in the past year and appeared likely to push the escalating conflict closer to full-fledged war. Iran announced on Saturday that a prominent general in its paramilitary Revolutionary Guard, Abbas Nilforushan, sanctioned by the US, also died in the airstrike.
