The Lebanese military has launched further attacks against Islamic militants in a camp in north Lebanon.
Three months of bombardment have left Nahr al-Bared in ruins
Lebanese army helicopters and tanks have struck against positions held by Fatah al-Islam gunmen inside the Nahr al-Bared Palestinian refugee camp.
On Tuesday, a deal was reached to let militants' families leave the camp safely, but negotiators say the phone contact has since broken down.
Nearly 300 people - mostly soldiers and militants - have died in the fighting.
Most of the 40,000 Palestinian refugees living in Nahr al-Bared, near Tripoli, fled in the weeks after the conflict started in May.
About 80 civilians are believed to remain in the camp.
The Lebanese army has said it will not stop bombarding the camp until the militants surrender, something the gunmen have refused to do.
Fatah al-Islam is a radical Palestinian splinter group believed to have links with al-Qaeda.
Lebanese officials also say it has ties to Syrian intelligence.
The fighting at the camp is the worst violence in Lebanon since the end of its civil war in 1990. It has added to the current political instability in the country.
