Hamas sent a three-man team to Cairo on Friday for talks on consolidating a ceasefire with Israel which ended a 22-day assault on the Gaza Strip, a spokesman for the Islamist movement said. "They will have discussions with the Egyptian authorities to try to end the (Israeli) blockade and open the crossing points, including the Rafah terminal," on the Egyptian border, Fawzi Barhum said. Hamas has warned it will resume fighting if Israel does not open the crossings. Both sides have observed their own ceasefires since last Sunday when Israel ended Operation Cast Lead leaving a trail of devastation and 1,330 Palestinians dead, according to doctors. The Cairo government had sought a more formal ceasefire agreed by all sides.
