DAMATURU, Nigeria (AFP) - At least 150 people died in a "heinous" wave of gun and bomb attacks in northern Nigeria that were on Saturday claimed by the Islamist Boko Haram sect. President Goodluck Jonathan condemned the assaults which officials said included at least five suicide bomb blasts and "directed security agencies to ensure the arrest of perpetrators of these heinous acts," said a statement from his spokesman Reuben Abati. As corpses piled up in the morgue, a rescue agency official told AFP the body count stood at 150. "I was involved in the evacuation of corpses to the morgue. I personally counted 150 bodies," the official, speaking on condition of anonymity, said at the hospital. He said some families had already collected their loved ones for burial, reducing the number to 97 by end of the day. An AFP reporter counted 97 corpses still in the mortuary. The Red Cross earlier said the death toll stood at 63, while police spoke of 53, of whom 11 were members of its force. "From our inventory, 53 people have so far been killed in the attack," said local police chief Suleimon Lawal. The 15-nation UN Security Council released a statement saying it "condemned in the strongest terms" the attacks in Nigeria. The council expressed condolences to the families. A member of Nigeria's Boko Haram sect on Saturday claimed responsibility.
