Hamas has proposed a yearlong truce with Israel if it pulls its troops from Gaza as a senior Israeli defence official was due back in Cairo on Friday to discuss an Egyptian plan to end the war. Mussa Abu Marzuk, the Damascus-based deputy head of Hamas's powerful politburo, told foreign news agency the offer was made by a Hamas delegation during talks in Cairo with Egyptian officials. Hamas was waiting for Israel's response, he said early Friday. "We are waiting for an answer from Egypt after they talk to (Israeli envoy) Amos Gilad," Abu Marzuk said.
