Hundreds of peace Israeli protesters demonstrate on a street in Tel Aviv, on July 24, 2014, asking for the end of the Israeli military operation in Gaza. Fifteen Palestinians were killed today when an Israeli shell slammed into a UN shelter where hundreds of civilians had taken refuge, sending the death toll in Gaza soaring to 788 despite world efforts to broker a ceasefire.
