Several explosions were heard, as well as small arms fire, as the attack began at about 05:00 local time (00:30 GMT) at a military base of the Afghan National Army in the west of Kabul.
The militants are believed to have been heavily armed with rocket propelled grenade launchers. One attacker has been arrested while another is still fighting with security forces, officials said.
Security forces have blocked off all roads in the area, Afghan media outlet Tolo said. The president's spokesperson said that none of the attackers had been able to get further than the first gate, Tolo news reported. Afghan military institutions are frequently targeted by militants.
