BRITISH FOREIGN SECRETARY WILL SEEK URGENT ISRAEL-HAMAS CEASE-FIRE IN VISIT WITH MIDDLE EAST LEADERS

London — British Foreign Secretary David Cameron is visiting the Middle East to meet with regional leaders this week to call for an “urgent humanitarian pause” in Gaza.

Cameron’s first stop Wednesday is Israel, where he is expected to raise concerns about the high number of civilian casualties in talks with Prime Minister Benjamin Netanyahu and push for water and electricity to be restored to Gaza. He will stress the need for more crossing points to enable more aid deliveries to Gaza, including the port at Ashdod and the Kerem Shalom crossing.

“No one wants to see this conflict go on a moment longer than necessary. An immediate pause is now necessary to get aid in and hostages out. The situation is desperate,” he said in a statement. He added that a permanent cease-fire would require Hamas to relinquish its hostages and control in Gaza, as well as an agreement for the Palestinian Authority to return to the enclave.

Cameron is expected to visit Qatar and Turkey later in the week.
