Israeli troops entered the West Bank town of Qalqilya Sunday morning. According to Palestinian sources, troops placed a curfew on the city.
Also, soldiers continue to carry out house-to-house searches in the refugee camp located at the northern entrance to Bethlehem, reports said.
Elsewhere, Israeli soldiers withdrew later from the vicinity of a mosque in Tubas, after finding that a wanted Palestinian was not holed up inside, media reports said. Palestinian sources said soldiers were after Islamic Jihad member Muhammad Al-Kilani.
They surrounded the mosque in Tubas for about an hour, believing he was holed up inside, but then it turned out he was not at the site.
In related news, the Israeli forces detained four Palestinians in Hebron and 26 in Bethlehem over the weekend.
Meanwhile, the Israeli army imposed a total naval closure of the Gaza Strip coastline Saturday, one day after four navy soldiers were injured when a Palestinian boat laden with explosives blew up in close proximity to a naval gunship off the northern coast of the Gaza Strip. The Islamic Jihad claimed responsibility for the attack.
Islamic Jihad leader in the Strip Abdallah Shami said Saturday that the attack, the first of its kind in the Al Aqsa Intifada, "gives a direction for further activities against Israel." He added the attack was successful and conveyed the group would implement further attacks against Israel in the same area.
