Smoke billows from a beach shack following an Israeli military strike, on July 16, 2014 in Gaza City which killed four children, medics said. All four were on the beach when the attack took place, emergency services spokesman Ashraf al-Qudra said, with several injured children taking refuge at a nearby hotel where journalists were staying.
