United Nations ? The U.N. Security Council voted unanimously Friday to keep peacekeepers in Lebanon for another 12 months, recognition that the country remains unstable more than a year after Israel’s war with Hezbollah.

The force was deployed after the war to help Lebanese troops extend their authority into the south for the first time in decades, and create a buffer zone free of Hezbollah fighters.

The resolution says the 13,600-strong U.N. force known as UNIFIL has helped 15,000 Lebanese troops establish “a new strategic environment” along Lebanon’s southern border with Israel, although more needs to be done to clear the area of unauthorized fighters and weapons. It did not elaborate on either point.

Syria and Iran have denied moving weapons into Lebanon, and Russia and South Africa objected to the U.S. raising what they called an unrelated issue. Lebanon’s U.N. envoy chose not to speak to the council or to reporters.
