The cease-fire started at 8 p.m. ET), according to Ayman Taha, a spokesman for Hamas -- the entity that runs the Palestinian territory of Gaza. It came after three Palestinians died in violence on Saturday in Gaza, including a 4-year-old boy and a militant. Israeli Prime Minister Benjamin Netanyahu's office refused to comment on the truce. Earlier Saturday, Israeli Defense Minister Ehud Barak, IDF Chief of Staff Banny Gantz and other senior security and intelligence officers held an "urgent" meeting over the violence. Palestinian medical officials said Israeli artillery fire from a tank at the Israeli-Gaza border killed the 4-year-old boy and badly injured two other civilians. The incident occurred east of Khan Younis in southern Gaza. Another drone attack on Gaza City killed a militant on a motorcycle. At least 10 others were wounded in the hit, which also damaged a nearby building. The militant, Osama Mahmmoud Ali, is a member of the Al-Nasser Salah al-Deen Brigades, the military wing of the Popular Resistance Committees, which lost one of its leaders in a similar strike Friday. An Israeli drone killed one man when it hit a militant group east of Beit Lahiya, in northern Gaza, according to medical sources in Gaza. Another drone fired a missile at a car in the Zeitoun neighborhood south of Gaza City, injuring three people. More than 15 rockets had been fired into Israel on Saturday morning alone, the IDF said. During the past week over 150 rockets hit Israel. The military said one of its strikes targeted a "terrorist squad" in northern Gaza preparing to fire a rocket into Israel. The IDF said it "will not tolerate any attempt by terrorist groups to target Israeli civilians and IDF soldiers, and will continue to operate against those who use terror against the State of Israel. The Hamas terror organization is solely responsible for any terrorist activity emanating from the Gaza Strip.
