It's a world away from the glitz and glamour of "Baywatch", but in time of war Gaza's most devoted lifeguard is passionate about keeping the beach a little bit safer. "I only love two things in my life: rescue work and people," said Mohammed Bar, 21, dressed in black trunks and a white municipality T-shirt as he scans the horizon from his watchtower. More than 2,140 Palestinians were killed during 50 days of violence in Gaza that finally ended on Tuesday when a long-term truce came into force. He would love a jet ski, he says, but Israel's eight-year blockade on Gaza and a lack of cash have put paid to that.
