A resounding explosion was heard across the city followed immediately by gunfire between security forces and an unknown number of attackers in the west of Kabul.
The fighting was concentrated near a district police headquarters located not far from a military training school, according to one police official, who spoke on condition of anonymity because he was not authorized to talk to the media.
A security official said one attacker was barricaded inside the police building.
A separate attack appeared to have targeted an office of Afghanistan's intelligence agency on the eastern outskirts of Kabul. However a senior army official said that attack appeared to have been quickly suppressed.
The Taliban, who sometimes exaggerate the impact of their operations, said the attacks had caused heavy casualties but there was no immediate comment from police and no official word on casualties.
The attacks come shortly ahead of the period when the Taliban, seeking to reimpose Islamic law after their 2001 ouster, announce their spring offensive and underline warnings from Afghan officials that they face a very difficult campaign season.
Government forces have struggled to control the Taliban insurgency since the NATO-led coalition ended its combat mission in 2014. According to U.S. estimates, they now control less than 60 percent of the country although they have managed to hold on to all of the main provincial centers.
