Seven Afghan police officers died and eight others were wounded when two men they had put up in their police station attacked them in the southern province of Kandahar, an official told Efe.
The attack occurred Monday night in the Arghestan district, provincial government spokesman Javed Faisal said.
The attackers, who were being housed in the Afghan security forces' post, acquired weapons there and opened fire on the officers, Faisal said.
Authorities have not yet determined if the attack was launched by Taliban insurgents who infiltrated the station, but so far the rebel group has not claimed responsibility for the attack.
The fundamentalists, however, had placed emphasis in the past on infiltrating fighters into the ranks of the Afghan army and police.
Separately, five security guards were killed Monday morning when a roadside bomb exploded as their vehicle was passing by north of Kabul, the police chief in Parwan province told Efe.
The incident occurred in the Qarabagh district, which separates Kabul and Parwan, and the victims were escorting top officials of a telephone company, Roshna Khalid said.
The war in Afghanistan is going through one of its bloodiest periods almost 12 years after the U.S. invasion that resulted in the fall of the Taliban regime. EFE
