Amid fears of an expanding war in the Middle East following mass detentions of bombs surreptitiously planted in Hezbollah communication devices, Israel continued its assault of the Iran-backed militia overnight.

As tensions remained high Friday between Hezbollah and Israel, international leaders called for both sides to seek paths to de-escalate the conflict.

Israel’s military said the strike targeted a senior Hezbollah member wanted by the U.S. for a series of bombings in the 1980s.
