The mother (C) of Palestinian Boy Mohammed Al KHodary 17 years, who medics said was killed by an Israeli air strike, is comforted as she mourns next to his body during his funeral in Gaza City August 24, 2014. Israel launched more air strikes on Gaza on Sunday after taking its military campaign to a new level by flattening a 13-storey apartment tower following a warning to residents to evacuate. Palestinian militants kept up their cross-border rocket fire in what has become a conflict of attrition that has defied attempts by regional power Egypt to broker a durable truce in fighting now in its seventh week.
