Beirut — Lebanon condemned an Israeli "aggression" after two drones Sunday targeted the Beirut stronghold of the Iran-backed group Hezbollah, warning of further regional tensions.

Hezbollah, considered a terrorist organization by the United States, is a major political actor in Lebanon and a key backer of the Damascus regime in war-torn Syria.

The early morning incident in south Beirut came hours after Israel said it had conducted air strikes in neighboring Syria to prevent an Iranian force from launching an attack on the Jewish state.

A war monitor said the air raids in the southeast of Damascus killed two Hezbollah members and one Iranian among five fighters.

Lebanon's army said "two drones belonging to the Israeli enemy violated Lebanese airspace... over the southern suburbs of Beirut", a Hezbollah stronghold in the capital.

"The first fell while the second exploded in the air causing material damage," he said.

Lebanon's President Michel Aoun, said the drone incursion targeted "stability and peace in Lebanon and the region".

Prime Minister Saad Hariri, condemned a "blatant attack on Lebanon's sovereignty". "This new aggression... forms a threat to regional stability and an attempt to push the situation towards more tension," he said.

Hariri also charged that it was in violation of UN Security Council Resolution 1701 that ended the 2006 war between Israel and Lebanon's Hezbollah. That 33-day war killed 1,200 in Lebanon and 160 in Israel. AFP
