Kabul, Afghanistan (CNN) -- Four terrorists and nine others were killed Saturday during an attack inside a Kabul police station, a spokesman for the Interior Ministry said.
The victims included three policemen, one intelligence officer and five civilians, spokesman Sediq Sediqi said. A dozen others, including two policemen, were wounded in the attack.
"The standoff is over and all the terrorists (have) been shot to death by Afghan forces," spokesman Sediqi said.
A suicide bomber was killed after detonating an explosive device attached to his vest, while three other terrorists working with him opened fire at Afghan security forces, Sediqi said.
Sediqi said the assailants wore military uniforms, but that he could not confirm who the attackers were.
Taliban spokesman Zabiullah Mojahed said the Islamist militant group is responsible for the attack, part of an effort to target government buildings in the Afghan capital.
Separately, at least three private security contractors were killed and two others injured Saturday from a pair of explosions in Afghanistan's Ghazni province, the Interior Ministry said.
In both attacks, security vehicles were struck.
In a statement, the Interior Ministry said it "condemns this inhumane and coward action of insurgents ... and expresses its sincere condolences to the families of the victims" from the Ghazni attacks.
