But Israeli officials have agreed to a plan by the US which could help free Palestinian leader Yasser Arafat from the siege in his Ramallah headquarters.
He has been trapped there since March.
The plan would mean US or UK officials would protect four Palestinians who killed an Israeli politician last October.
Palestinian officials are said to be thinking about whether to accept the deal or not because they don't want the men handed over to Israel.
Israeli soldiers are also hunting for a Palestinian man who disguised himself as an Israeli soldier and broke into a Jewish area near Hebron on Saturday.
He killed four Israelis who live there, including a five-year-old girl.
