Militants have attacked an army outpost and a gold mine run by precious stones miner Gemfields Group in the northern Mozambican district of Montepuez in Cabo Delgado province, privately-owned radio station Zumbo FM has reported.
The early morning attack took place in the village of Nairoto at around, the radio station said.
An unspecified number of police and forest rangers were killed in the attack, sources told the station, while staff were evacuated from the mine.
The attack appeared to have been carefully planned, the station said, as hours before targeting the mine, militants targeted a nearby army outpost.
Montepuez district administrator Isaura Maquina confirmed the attacks but provided no details on casualties.
Cabo Delgado has been the epicentre of militant violence since 2017.
