A military official says the head of U.S. forces in Africa has donated armored vehicles to Cameroon to aid the country's fight against Boko Haram.

Col. Jean Jacques Fouda, Cameroon's official in charge of military hardware, said Saturday that the vehicles given during a visit Friday by Gen. David Rodriguez could "fight against mines" and are some of the best the country had ever acquired. He did not specify how many were donated.

The White House announced this week that 90 U.S. troops are headed to Cameroon, which has been regularly targeted by the Nigeria-based extremists and is contributing to a regional force to fight them.

The Americans, the vanguard of a group that expected to reach 300, will conduct airborne intelligence, surveillance and reconnaissance in the region.
