DAKAR, Feb 16 (Reuters) - About 100 U.S. forces personnel have arrived in Nigeria, the West African country's defense headquarters spokesman said on Monday, as Washington scales up a military operation against what it regards as extremism.
In December, the U.S. carried out strikes targeting Islamic State-linked militants, and a small U.S. team of military personnel has been operating on the ground to help boost Nigeria's intelligence capabilities.
