TRIPOLI - Ten kilos of explosives were found during a raid on a home in a Palestinian refugee camp in northern Lebanon on Thursday, a Palestinian official said.

"Ten kilos of explosives, six modern timer systems, 10 remote controls and a large number of grenades were found in an apartment in Beddawi," the official said on the condition of anonymity.
Beddawi is one of 12 Palestinian camps in Lebanon and home to an estimated 16,000 refugees.
The official said security forces stormed into the apartment based on information from a Palestinian arrested last week in a raid that turned deadly when a passerby was killed in a shootout between security forces and the wanted men.

The Lebanese army does not enter the camps, leaving responsibility for security to Palestinian factions, but extremists believed to have links with Al-Qaeda have settled in some of the shantytowns.
Beddawi's population is thought to have swelled after an influx of refugees from the nearby Nahr al-Bared camp which was almost completely destroyed after a 15-week battle last year between the Lebanese army and an Al-Qaeda inspired militant group.
