Shukr was previously sanctioned and designated a terrorist by the U.S. government. During the 1983 bombing 241 American personnel were killed. He also aided Hezbollah forces fighting rebels in Syria, according to the Justice Department notice offering a $5 million reward for information about him.

Lebanon has been on edge, speculating about Israel’s response following a missile strike on Saturday that hit a football field in Majdal Shams, a Syrian town in the Golan Heights.
Israel blamed Hezbollah for the attack, a charge the Iran-backed faction denied. A day later, Israel’s air force reported hitting seven Hezbollah targets deep in Lebanon.

Targeted Strikes
Tuesday evening’s airstrikes appeared to be more limited but focused, targeting a residential building in Beirut’s Dahieh suburb. Residents near the blast site reported hearing three explosions, and the state-run National News Agency attributed the attack to a drone firing three missiles.
