The latest round of talks in Cairo to restore the defunct Gaza ceasefire and free Israeli hostages ended with no apparent breakthrough, Palestinian and Egyptian sources said on Monday. Hamas has stuck to its position that any agreement must lead to an end to the war in Gaza. Israel, which restarted its military campaign in Gaza last month after a ceasefire agreed in January unravelled, has said it will not end the war until Hamas is stamped out. Despite the fundamental disagreement, a Hamas delegation showed some flexibility over how many hostages it could free in return for Palestinian prisoners held by Israel should a truce be extended.
