The Israeli army arrested five Palestinians overnight inside the Qalandya refugee camp north of Jerusalem in the West Bank.
"The five Palestinians were suspected of terrorism and criminal activities and were arrested during a joint operation of Israeli paratroopers, police and borderguards," an army statement said.
Meanwhile, the US peace envoy Mr Anthony Zinni is due to return to the Middle East on Thursday.
A US embassy spokesman said Mr Zinni would be back for an initial four or five days, and would probably "be coming and going" in a bid to push the Palestinians to stick to their ceasefire while urging Israel to ease restrictions on the territories.
Chief Palestinian negotiator Saeb Erakat said Mr Zinni would resume his mission of securing a lasting ceasefire that will allow peace talks to resume.
