Israel and Hezbollah agreed to a U.S.-brokered 60-day ceasefire that calls for a phased Israeli military pullout after more than a year of war, in keeping with a 2006 U.N. Security Council resolution that ended the their last major conflict.

Under the agreement, Hezbollah fighters must leave positions in south Lebanon and move north of the Litani River, which runs about 20 miles (30 km) north of the border with Israel, along with a full Israeli withdrawal from the south.

In a statement, UNIFIL voiced concern over what it said was continued destruction by Israeli forces of residential areas, farmland and infrastructure in south Lebanon, deeming this a violation of U.N. Resolution 1701.

“UNIFIL continues to urge the timely withdrawal of the Israel Defense Forces and the deployment of the Lebanese Armed Forces (in place of Hezbollah) in southern Lebanon, alongside the full implementation of Resolution 1701 as a comprehensive path toward peace,” the statement said.

The Israeli military said it was looking into UNIFIL’s criticism and declined further comment for the time being.

Under the terms of its truce with Hezbollah, Israeli forces can take up to 60 days to withdraw from south Lebanon but neither side can launch offensive operations.

Lebanon’s army said it was following up with UNIFIL and the committee supervising the agreement regarding what it said was a deepened incursion of Israeli forces into some areas of southern Lebanese areas.

UNIFIL reiterated readiness to monitor the area south of the Litani River to ensure it remains free of armed personnel and weapons, except those of Lebanon’s government and UNIFIL.

The ceasefire marked the end of the deadliest confrontation between Israel and Hezbollah since their six-week war in 2006. However, Israel has continued military operations against Palestinian militants in Gaza.
