Hamas leaders-in-exile vowed to fight on until Israel met their demands: a truce in return for Israeli troops pulling out, and an end to a crippling economic blockade:“We have nothing new to offer,” said Osama Hamdan. “We are not going to go back to the start of the discussions and dialogue. Either we hear what we want or the result will be continuing the confrontation on the ground.” Since Hamas banished its rival Fatah in 2007, Israel has sealed the frontier with Gaza, forcing Hamas to smuggle food and weapons – including rockets – through tunnels from Egypt. The US has agreed to provide technology and training to detect tunnels .. but the Egypt’s president is adamant he would not allow outsiders in to monitor what’s happening on .. and under .. the ground: “Because Egypt, in its efforts to end the aggression, is working to secure its borders with Israel and the Gaza strip and will never accept the presence of international monitors on its territory,” said President Mubarak. “And I say that this is a red line that I will never allow to be crossed.” Britain, France and Germany have offered to send warships to the region to try to prevent arms being smuggled into Gaza. And Egypt has invited several world leaders including Britain’s Gordon Brown, France’s President Sarzoky, Palestinian President Abbas and UN Secretary-General Ban Ki-moon to co-ordinate their responses to the fighting in Gaza.
