Bombs are falling on Gaza again. Who are the hostages still remaining in the besieged strip?
The remains of a tank shell, which police said was fired by Israeli troops, are seen on the fourth floor of Al-Wafa rehabilitation hospital in the east of Gaza City July 16, 2014. Patients were evacuated from the fourth floor to the ground floor after the strike on the hospital, which was earlier warned of the impending Israeli strike, medics said. Israeli shelling killed four boys on a Gaza beach on Wednesday, a local health official said, and Palestinian militants fired a further 70 rockets into Israel after a failed Egyptian attempt to halt more than a week of warfare.
