Fighting has subsided in Gaza after Hamas backed a 24-hour truce with Israel, but there's still no sign of comprehensive deal to end the near three-week-long conflict.
Hamas says it had endorsed a call by the UN for a pause in the fighting in light of an upcoming Muslim holiday, which starts on Monday.
Some firing has been reported on both sides since Hamas agreed to lay down its weapons.
Israeli Prime Minister Benjamin Netanyahu says he doubts the validity of the truce, adding that Israel would take whatever action is necessary to protect the Israeli people.
Over one-thousand Palestinians, including many women and children, have been killed in the 20-day conflict.
Forty-three Israeli soldiers have died, along with three civilians killed by rocket and mortar fire out of Gaza.
