Political talks kick-off as army pushes deeper into Nahr al-Bared refugee camp.
The advance marked a major step for the army in the battle to crush fatah al-Islam and a rare incursion by troops into a Palestinian refugee camp in Lebanon.
A 1969 Arab agreement banned Lebanese security forces from entering Palestinian camps.
The agreement was annulled by the Lebanese parliament in the mid-1980s but the accord effectively stayed in place.
Commandos exchanged automatic rifle fire and grenades with fighters at buildings and alleyways leading to the centre of Nahr al-Bared while army artillery and tanks pounded other areas.
The vast majority of Nahr al-Bared’s 40,000 refugees had fled in the early days of the fighting which has left the camp in ruins.
The Unifil vehicle damaged near Tyre was hit by an explosion near the Qasimiya bridge over the Litani river.
“We can confirm an explosion in the area of Qasmiyeh bridge which slightly damaged a Unifil vehicle of the Tanzanian battalion,” spokeswoman Yasmeena Bouziane said.
The blast came less than a month after a car bombing cost the lives of three Spanish and three Colombian members of Unifil on June 24.
