CAIRO/LONDON (AFP) - Egypt on Tuesday welcomed statements by Hamas leaders that they were ready to seal a unity deal with the rival Fatah faction but said Cairos blueprint for Palestinian reconciliation was not up for negotiations. Successive statements from several Hamas leaders regarding their willingness to achieve Palestinian reconciliation are welcome, Foreign Ministry spokesman Hossam Zaki said. But he ruled out requests by Hamas to modify an Egyptian-drafted document to seal the reconciliation between the group and Fatah, the mainly secular party of Palestinian president Mahmud Abbas. Meanwhile, negotiations between Hamas and Israel over a prisoner swap involving captive Israeli soldier Gilad Shalit have stopped, a senior official in the movement said in an interview aired Tuesday. Up to this moment, we fail to achieve this process, Mahmud Zahar told the BBC. After the interference of (Israeli Prime Minister Benjamin) Netanyahu, there was a big regression and retraction. For this reason, everything has stopped, said Zahar, one of the leaders of Hamas in its Gaza Strip stronghold. Shalit, now 23, was captured by Hamas fighters from two other groups in a cross-border raid from Gaza in June 2006. Although Israel is reportedly prepared to release about 450 prisoners in exchange for Shalit, Netanyahu has vowed not to free several high-profile Palestinians who Hamas insist must be part of any deal.
