Egypt\'s Ansar Beit al-Maqdis group has claimed responsibility for firing a Grad rocket at the Red Sea town of Eilat overnight. The announcement of the group came in a statement circulated today on various websites. Israel intercepted and destroyed a rocket fired from Egyptian territory at the Red Sea town of Eilat overnight, Israeli public radio said Tuesday. A group of fighters said earlier they had fired a Grad rocket on Eilat in retaliation for an alleged Israeli air raid. The rocket, fired from the Sinai, was a quick response to the last crime by the Jews after one of their drones bombed the Sinai peninsula killing four mujahideen on Friday, said the statement. Militants based mainly in north Sinai near Israel\'s border have escalated attacks on security forces and other targets since July 3, when the army ousted Islamist president Mohamed Morsi and installed a new government in Cairo.
