Diplomatic efforts in Gaza move into high gear

Diplomatic efforts to end the fighting in Gaza are in high gear. United Nations Secretary-General Ban Ki-moon is in the region for a series of meetings urging a cease-fire between Israel and Hamas. Despite these calls for peace, Israel’s offensive continues with fighting raging in Gaza City and reports of Israeli shelling of the U.N. headquarters in Gaza. For the latest on the troubling situation in Gaza we turn to Laura Trevelyan, the BBC’s United Nations correspondent, who joins us from the bus where she is traveling with Ban Ki-Moon from Tel Aviv to Jerusalem.
