Top UN and US diplomats headed to Cairo to broker Gaza ceasefire

The UN chief and the US secretary of state are heading to Cairo to try to end two weeks of Israel-Hamas fighting in Gaza which has killed at least 500 Palestinians and 20 Israelis and displaced tens of thousands of people.

The new ceasefire efforts by Ban Ki-moon and John Kerry followed the deadliest day of fighting since the escalation erupted on July 8, including a reported Israeli shelling of a hospital in the central Gaza Strip.
