Four people have been killed when a police station and local government office were destroyed by gunmen in north-eastern Nigeria, police say.
The attacks came in the town of Song, near the border with Cameroon.
A policeman, a soldier, a civilian and his grandchild were killed, the Adamawa state police spokesman told the BBC.
He did not blame any group but militants from the Boko Haram Islamist group have staged frequent attacks in northern Nigeria.
They have often targeted Adamawa state but this is believed to be the first time Song has been attacked.
Local residents say some of those who died were burnt to death.
Police spokesman Mohammed Ibrahim told BBC Hausa that extra security forces had been sent to the area.
He said there had been no arrests.
Last week, there was a similar attack in Maiha, also in Adamawa state.
Violence linked to the Boko Haram insurgency – a group seeking to impose Islamic law on the country – has claimed some 3,000 lives in recent years, human rights groups say.
