The US has agreed to boost the capabilities of Nigerian security forces, as gunmen opened fire and threw explosives at a police station in the city of Kano, residents said, four days after coordinated bombings and shootouts killed 185 people there.
"It was around 6:30 (pm) when people were preparing for the evening prayers and a large group of gunmen arrived in the area and opened fire on the police station and threw in bombs," said a resident of the Sheka area of the city.
