Hamas leader Khaled Mashaal accused Israel on Tuesday night of preventing the release of abducted soldier Gilad Schalit. In an interview to TV station Euronews, Mashaal said "Those who are blocking the negotiations on the release of Gilad Schalit are our Zionist enemies." "It is Olmert and his team who are putting up the barricades and not listening to our demands," Mashaal said. "We are happy to go on with the Egyptian mediation on the subject of prisoner release. But when we present our list, Israel refuses." "When Israel replies to our demands we will obviously liberate Gilad Shalit as soon as possible," he added.
