Gunmen in south-eastern Nigeria have attacked a US convoy, killing four people, local police say.

They say two of the victims of Tuesday’s attack in the Anambra state were US consulate employees, while the other two were police officers.

The attackers kidnapped three other people, and set their vehicle on fire.

Washington says no US citizens were in the convoy, which was travelling in the state plagued by violence and separatist insurgency.

Nigerian police say the attack happened on the Atani-Osamale road in Ogbaru region.
