Rocket hits UNIFIL headquarters in south Lebanon

A rocket hit the headquarters of the U.N. peacekeeping mission in southern Lebanon in the coastal town of Naqoura as clashes between Hezbollah and its allies and the Israeli military escalated Sunday.

The U.N. mission said no one was hurt even though the peacekeepers were not in shelters. It did not specify where the rocket came from but expressed disappointment saying that despite the mission's efforts to get the sides "to de-escalate the situation,” the violence continues.

Some local Lebanese media said the rocket was fired from positions of Palestinian Hamas militants in southern Lebanon, intending to reach Israel but that it fell short. The Associated Press could not confirm the source of the rocket.

The U.N. peacekeepers have been patrolling the Lebanon-Israel border as tensions flare. Hezbollah, a key ally of Hamas, has vowed to retaliate against Israel should they launch a ground offensive into the blockaded Gaza Strip.

The U.N. mission, known as UNIFIL, was created to oversee the withdrawal of Israeli troops from southern Lebanon in 1978 and expanded its role after a monthlong in 2006 war between Israel and Hezbollah that ended in a stalemate.
