Dozens of Boko Haram fighters thought killed by Niger and Chadian forces after attacks on Bosso and Diffa, near Nigerian border
The Islamist militant group Boko Haram has about 4,000-6,000 “hardcore” fighters, US intelligence officials have said.
In an assessment of the group, whose five-year uprising including massacres and kidnappings has spread from Nigeria into neighbouring countries, the officials said they did not believe it posed major threat to Nigeria’s oilfields.
