Palestinians are pictured through a damaged wall as they flee their houses following an Israeli ground offensive in Rafah in the southern Gaza Strip July 18, 2014. Israel launched a Gaza ground campaign after 10 days of bombardments from the air and sea failed to stop militants’ rocket attacks, stepping up an offensive that already has taken a heavy toll in civilian lives. Gaza residents and medical officials reported heavy shelling along the eastern border from the southern town of Rafah to the north of the strip. Israel signalled the invasion would be limited in scope – targeting tunnels dug by gunmen – and said it was not intended to topple Hamas, the Gaza Strip’s dominant Islamist group.
