Investigators probed a Nigerian Islamist sect on Monday over the suicide bombing of UN headquarters here that killed at least 21 people in one of the bloodiest attacks targeting the world body globally. Fresh violence hit Sunday when gunmen stormed the home of a local government chairman in the northeast and shot him dead. An attacker also threw a bomb onto the property of an ex-government minister, but there were no injuries. The UN’s deputy chief held talks with Nigerian President Goodluck Jonathan on Sunday and afterward said the “perpetrators must be brought to justice”, while vowing that the attack would not deter the work of the United Nations.
