Lebanon ? Islamic militants killed a soldier Thursday in a Palestinian camp where violence has raged for three weeks, and a bombing in a Christian town killed at least one man in the latest in a string of explosions that has shaken Lebanon since the fighting erupted.

In eastern Lebanon, an army raid on a suspected militant hideout uncovered vehicles rigged with explosives that were hidden in a garage with several rockets.

Tensions have been high in Lebanon since fighting broke out May 20 between the army and Fatah Islam militants in the northern Nahr el-Bared refugee camp. There also have been clashes at the Ein el-Hilweh camp in the south and several bombings in the Beirut area, sparking fears of spreading chaos.

The soldier was shot by Fatah Islam snipers in the Nahr el-Bared camp, security officials said. Earlier, the al-Qaida-inspired militants attacked an armored personnel carrier, wounding three soldiers, and the army retaliated by firing artillery, tanks and machine guns.
