UNITED NATIONS (AP) — The UN Security Council voted unanimously Thursday to extend the peacekeeping mission in Lebanon for another year, saying the situation there remains a threat to international peace and security.

The council expressed “deep concern” at violations of the 2006 resolution that ended the war between Israel and Iranian-backed Hezbollah.

The UN force, which has been in southern Lebanon since 1978, was expanded after the 2006 war so peacekeepers could deploy along the border with Israel to help Lebanese troops extend their authority into the south for the first time in decades.

The resolution by the council extends the force’s mandate until Aug. 31, 2013.

The force has an authorized strength of 15,000 troops. The UN says 11,530 troops were on the ground at the end of July.
