Palestinian factions meeting for talks in Cairo appear to have failed to agree to a full ceasefire in the Middle East. Armed groups have agreed only to stop bomb attacks against Israelis, implying they could continue to attack troops and settlers. The decision is a blow to Prime Minister Ahmed Qurei, who hoped to use a ceasefire as a basis for talks with his Israeli counterpart Ariel Sharon. Sharon's deputy has said he doubts the talks will end attacks on Israel. Correspondents say the outcome in Cairo has cast doubt over Qurei's presence at the talks. He may still attend the closing ceremony on Sunday after arriving in the Egyptian capital late on Saturday. **Trap*** The talks, being mediated by Egyptian officials, have been described as heated. A representative of Palestinian leader Yasser Arafat's Fatah movement, one of six groups backing a full ceasefire, briefly stormed out of a meeting in anger at what he called the inflexibility of the armed groups. Hamas and Islamic Jihad have indicated, along with three other smaller factions, they may be willing to accept a truce with Israel if it agreed, in turn, to halt military activity. "We will only accept a ceasefire this time after Israel initiates a total ceasefire," a senior Hamas official told Reuters news agency. "We will not fall into the trap of the previous truce when we adhered to a truce while Israel continued its aggression." Fatah delegate Ahmed Ghneim said the factions had not got what they wanted. "Nothing is impossible but it is looking less likely that we will have a comprehensive ceasefire," he said. **PHOTO CAPTION*** Senior official in the Palestinian Muslim Islamic Resistance group Hamas, Mohammad Nazzal speaks on his phone before an interview with Reuters in Cairo December 5, 2003.
