A Palestinian woman flees her house following what witnesses said was a nearby air strike on an apartment in Beit Lahiya in the northern Gaza Strip August 10, 2014. Israel said on Sunday it was prepared for protracted military action in Gaza and would not return to Egyptian-mediated ceasefire talks as long as Palestinians kept up cross-border rocket and mortar fire. Israeli air strikes and shelling killed three Palestinians in Gaza on Sunday, including a boy of 14 and a woman, medics said, in a third day of renewed fighting that has jeopardised international efforts to end a more-than-month-old conflict. Since the last truce expired, Palestinian rocket and mortar salvoes have focused on Israeli kibbutzim, or collective farms, just across the fortified border in what appeared to be a strategy of sapping the Jewish state’s morale without triggering another ground invasion of the tiny Gaza Strip.
