The United States added the Nigerian-based militant groups Boko Haram and Ansaru to its list of terrorist organizations on Wednesday, the State Department said, according to dpa. Boko Haram is responsible for thousands of deaths in Nigeria in attacks on military, government and civilian targets, the State Department said. Ansaru is a splinter faction of Boko Haram. The move prohibits Americans from supporting the groups and freezes all property they may have in the United States. -- SPA 19:51 LOCAL TIME 16:51 GMT تغريد
