Beirut - At least one person was injured on Friday when a bomb exploded inside the Ain el Hilweh Palestinian refugee camp in southern Lebanon, Palestinian sources said.

The bomb exploded inside the camp, wounding at least one person.

This comes weeks after another explosion ripped through the camp on September 23, killing one man and injuring four others.

For the past two weeks, members of the mainstream Fatah movement and others who belong to Jund al Sham, a fundamentalist group with links to the al-Qaeda terror network, have clashed in the area where the explosion took place.

There are some 12 refugee camps around Lebanon, but security inside the shanty towns is in the hands of the Palestinian factions. (dpa)
