Relatives of Palestinian woman Amani Baraka, whom medics said was killed in an Israeli air strike, mourn during her funeral in Khan Younis in the southern Gaza Strip August 10, 2014. Israeli air strikes and shelling killed three Palestinians in Gaza on Sunday, medics said, in a third day of renewed fighting that has jeopardized international efforts to achieve a lasting ceasefire in a more than month-old conflict. Palestinians kept up rocket and mortar fire that, since the last truce expired on Friday, has focused on kibbutzim, or collective farms, just across the border in what appeared to be a strategy of sapping Israel's morale without triggering another ground invasion of the tiny Gaza Strip.
