Palestinian protesters walk near a burning rubbish bin during clashes with Israeli troops at a protest against the Israeli offensive in Gaza, in the West Bank town of Bethlehem August 1, 2014. Israel declared a Gaza ceasefire over on Friday, saying Hamas militants breached the truce soon after it came in effect and apparently captured an Israeli officer while killing two other soldiers. The 72-hour break announced by U.S. Secretary of State John Kerry and U.N. Secretary-General Ban Ki-moon was the most ambitious attempt so far to end more than three weeks of fighting, and followed mounting international alarm over a rising Palestinian civilian death toll.
