An Israeli helicopter launched an air strike along the Gaza Strip's border with Israel early Saturday, officials said, killing a Palestinian and wounding two others and further straining a fragile cease-fire. In the West Bank, meanwhile, Israeli troops clashed with Palestinian gunmen, wounding one of the area's most wanted person, Zakariye Zubeydi, a leader of the Al Aqsa Martyrs' Brigades, according to a foreign agency report.
