CAIRO (AFP) - Egypt has asked Gaza’s Hamas rulers for information on three members of a group suspected of involvement in a deadly attack on a military outpost, a senior security official said. He said Egyptian authorities had received a list of nine suspects from Israel, and asked the Palestinian movement Hamas to provide information on three of the men. They are believed to be affiliated with the Army of Islam, a small radical group which Egypt has blamed for several attacks in past years. The Egyptian military has been bolstering its presence in the Sinai with tanks and helicopters after Sunday’s unprecedented ambush on a border guard outpost near the borders of Gaza and Israel.
