Hezbollah chief Hassan Nasrallah has warned that the group is bound to respond to Israel’s killing of its top military commander, saying his death and that of the Hamas leader “crossed” red lines, AFP reports.

“The enemy, and those who are behind the enemy, must await our inevitable response,” he said in a speech broadcast at the funeral of Hezbollah military commander Fuad Shukr.

“You do not know what red lines you crossed,” he said, addressing Israel after separate strikes in Beirut and Tehran killed Shukr and Hamas political leader Ismail Haniyeh.

“We, on all the support fronts, have entered a new phase,” Nasrallah said, referring to Hezbollah and other Iran-backed groups that have targeted Israel in support of Hamas.
