Two Lebanese soldiers have been killed in fighting between government forces and al-Qaida-inspired militants at a Palestinian refugee camp.

The two died early Tuesday as the army resumed shelling Fatah al-Islam militants in the Nahr al-Bared camp near Tripoli.

Meanwhile, a group of Palestinian mediators has met with militants inside the camp to discuss details of a truce.

According to sources, the deal will include a ceasefire followed by the militants' disarmament. The Lebanese army is now reviewing the proposal.

More than one month of fighting at the northern Lebanon camp has killed at least 140 people, including 73 soldiers.

In another development, the United Nations has agreed to allow U.N. investigators help Lebanon probe last Wednesday's car bombing death of a leading anti-Syrian lawmaker.

The U.N. Security Council Monday approved Lebanon's request for assistance in investigating the assassination of lawmaker Walid Eido. The blast killed nine others, including one of Eido's sons.

The U.N. previously created an international commission to help probe the assassination of former Lebanese Prime Minister Rafik al-Hariri. Eido and Mr. Hariri were among several anti-Syrian Lebanese politicians who have been assassinated. Syria has denied any role in the killings.
