Israel-Gaza 72-hour ceasefire lasts less than 72 minutes
At least four Palestinians have been killed by Israeli tank fire barely one hour after Israel and Hamas began observing a three-day ceasefire, Gaza officials have said, The Daily Mail reported.
Health Ministry official Ashraf al-Kidra and Gaza police spokesman Ayman Batniji said 15 other Palestinians were wounded in the shelling east of the southern Gaza city of Rafah.
Palestinian sources also claimed three other people were shot by Israeli sniper fire.
An Israeli army spokesman in Jerusalem said the military was looking into the incidents.
But U.S. secretary of state John Kerry had warned there were 'no guarantees' the lull would bring an end to the war which has so far killed more than 1,450 Palestinians and 60 Israelis.
