Kabul, Afghanistan (CNN) -- Three heavily armed militants attacked a guesthouse in northern Afghanistan on Tuesday, killing at least three guards and wounding 10 others, officials said.
The first attacker set-off an explosive device in a vehicle at the building's main gate, allowing three other militants to enter the compound and eventually detonate their bombs, an Interior Ministry statement said.
Nine civilians and one police officer were injured in the attack, according to Mohibullah Saidi, a spokesman for the Kundoz provincial governor.
The gunmen exchanged fire with police for at least two hours in an attack that the Taliban has claimed responsibility for.
