(CNN) -- A suicide car bomb targeting a military convoy killed seven Afghan police officers in northern Afghanistan on Thursday, authorities said.
The strike occurred in Aghantepa, a village in the Aman Sahib district of Kunduz province. A provincial official reported the attack, which was confirmed by the country's Interior Ministry.
Of the seven police killed, six were national police officers and one was a tribal police officer.
Seven civilians and six tribal police officers were injured, but there was no immediate word from NATO's International Security Assistance Force about whether international forces sustained casualties.
The attacker used a Toyota Corolla to conduct the strike, which government officials called a brutal act.
