ABUJA (Reuters) - Islamic State's West Africa branch claimed responsibility on Wednesday for a raid in Nigeria two days earlier in which it said 20 soldiers had been killed, and released a video purporting to show the execution of nine other Nigerian soldiers.
A security source and a humanitarian worker, both requesting anonymity because they were not allowed to speak to media, said insurgents struck the northeastern town of Gubio in Borno state on Monday evening, in vehicles mounted with heavy machine guns and on motorbikes.
