An Israeli soldier carries a shell at a mobile artillery unit while it fires towards the Gaza Strip August 1, 2014. Israel declared a Gaza ceasefire over on Friday and killed more than 50 Palestinians in renewed shelling, saying militants had breached the truce shortly after it began and apparently captured an Israeli soldier. 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.
