Jerusalem ? Israeli troops patrolling the West Bank city of Jenin killed one Palestinian militant and wounded two others in a shootout Saturday, hospital officials said, in one of several clashes overshadowing an agreement turning some Gaza Strip security duties over to Palestinians.

A member of the Al Aqsa Brigades, linked to Yasser Arafat’s Fatah movement, said the three militants opened fire on the troops, who then returned fire.

An Israeli tank also fired on stone throwers in Nablus, injuring six people, Palestinian witnesses said.

In the Gaza Strip, the army demolished three Palestinian houses it said Palestinian militants used as cover in an attempted infiltration of a Jewish settlement.

Late Saturday, Al Aqsa Brigade members said they fatally shot a Palestinian woman suspected of collaborating with Israel. The bullet-riddled body of Ikhlas Yassin, 35, who was kidnapped Friday, was found lying in the street in the West Bank town of Tulkarem.

The agreement giving security control in some Gaza Strip areas to the Palestinians is a trial for easing harsh Israeli restrictions imposed in the West Bank after a spate of suicide bombings in Israel.

Israel turned over security duties to Palestinian forces in the West Bank town of Bethlehem last week and was to take similar measures in Gaza.

The Israelis say if the Palestinians can stop attacks from those two places, they will ease restrictions in other parts of the West Bank, where Israel continues to control most main Palestinian population centers.
