A Lebanese soldier has been killed in sporadic fighting between the army and Islamist militants entrenched in a Palestinian refugee camp in Lebanon.
Thousands have fled the fighting in Nahr al-Bared in northern Lebanon
It is not known if there were any casualties among the militants.
For the past nine days, hundreds of soldiers supported by tanks have laid siege to the Nahr al-Bared camp where Fatah al-Islam militants are based.
Dozens have died, including civilians, although the UN estimates that about 25,000 people have now fled the camp.
But Nahr al-Bared houses around 31,000 people and some people remain trapped inside.
As calm returned on Tuesday, an International Committee for the Red Cross convoy entered the camp to deliver much-needed drinking water, food and medicine.
There has been sporadic fighting on almost a daily basis but few reports of the fierce gun battles witnessed during the earlier days of the stand-off, as negotiations continue.

Since Sunday a delegation of clerics from the Union of Palestinian Scholars has been leading mediation efforts with the approval of Lebanese officials, Palestinian factions and Fatah al-Islam.
"We are still at the beginning of the mediation road, but we are determined to continue and to work as fast as possible," AFP quoted cleric Shaykh Mohammad al-Hajj as saying on Monday.
The Lebanese government has accused Fatah al-Islam of being a criminal gang masquerading behind Islam and the Palestinian cause.
The militants say they will not surrender to what they call Zionist Americans and their loyalists.
The fighting at the camp is the bloodiest internal conflict in Lebanon since the civil war ended 17 years ago.
It began after security forces raided a building in Tripoli to arrest suspects in a bank robbery. Fatah al-Islam militants then attacked army posts at the entrances to the camp.
A large force of Lebanese troops hit back, bombarding the camp and storming a building on the outskirts of Tripoli.
