Update | Israel declares Gaza ceasefire over as 50 Palestinians die in renewed shelling
Gaza ministry says 50 killed by Israeli shelling; Israel says militants attacked its troops 90 minutes after truce began

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 US Secretary of State John Kerry and UN 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.
The ceasefire, which began at 8am local time had prompted Palestinian families to trek back to battle-devastated neighbourhoods where rows of homes have been reduced to rubble. It was to be followed by Israeli-Palestinian negotiations in Cairo on a longer-term solution.
Egyptian officials said the invitation to negotiators still stood, but some Palestinian representatives had asked for a postponement until Saturday or Sunday to allow a new truce to be reached.
The Israeli military said that 90 minutes into the truce, militants attacked soldiers searching for tunnels in the southern Gaza Strip used to infiltrate fighters into Israel.
