The United States Government has promised to help Nigeria apprehend the killers of its officials and two police officers in Anambra.

A gang of unknown assailants on Tuesday attacked a motorcade of two U.S. government vehicles in the Ogbaru Local Government Area.

The convoy was carrying 9 Nigerian nationals, five employees of the U.S. Mission and four members of the Nigeria Police Force (NPF).

The delegation was traveling in advance of a planned visit to a flood response project in Anambra sponsored by the American government.

A statement the consulate issued Wednesday night quoted Secretary of State, Antony Blinken saying America doesn’t yet know the motive for the attack and if it was targeted against the Mission.

“The assailants killed at least four members of the convoy. U.S. agencies are collaborating with Nigerian counterparts to ascertain the location and condition of victims unaccounted for.

“We condemn in the strongest terms this attack. We will work closely with our Nigerian law enforcement colleagues in seeking to bring those responsible to justice,” Blinken promised.

The U.S. said it has no greater priority than the safety and security of its personnel, expressing heartfelt condolences to the families of those killed in the attack.

The statement further reaffirmed America’s strong commitment to the people of Nigeria to assist in the fight against violence and insecurity.
