The Taliban has attacked government offices in Afghanistan's southern Helmand province, where the insurgents have been battling government forces for months.
A spokesman for Helmand's governor, Omar Zwak, said gunmen attacked the police headquarters and intelligence agency offices in Gereshk.
He said security forces repelled the attack on the intelligence facility.
The Taliban claimed responsibility for the attack, in which suicide bombers struck inside the police compound.
Jabbar Karaman, an MP appointed by President Ashraf Ghani to investigate the situation in Helmand, said seven attackers had been killed in the ongoing gunfight with police, as well as three police officers, with an unknown number of civilians caught in the crossfire.
