Palestinian sources in Lebanon estimate the number of Fatah al-Islam members remaining in the embattled Palestinian refugee camp of Nahr al-Bared at no more that 75.
On Wednesday at least 20 militants and other gunmen surrendered to the army in return for guarantees of a fair trial.
"The days of Fatah al-Islam are numbered," said Sultan Abul Aineyn, a Lebanon representative of the Palestine Liberation Organization.
The Lebanese military have been bombarding Nahr al-Bared since May 21, following a gun battle in the nearby town of Tripoli between Fatah al-Islam, believed to be linked to al Qaeda, and the Lebanese army.
Most Nahr al-Bared refugees have already fled to other camps. The death toll in the last two weeks is estimated at approximately 120 people.
