The Ashraf Ghani government has blamed the Pakistan-backed Haqqani network for the terror attack. However, the Taliban, has denied involvement in the attack on the Sikh shrine.
The gunmen attacked the gurdwara in Shor Bazar area at about 07:45 (local time) as 150 worshippers were inside the building.
"At least 11 people have been killed and 11 others wounded in attack at Dharamshala, a Sikh worship area in PD1 of Kabul," Tolo News quoted a security source as saying.
"Three attackers are still fighting with security forces and one has been shot. Foreign troops have also responded to the attack on Dharamshala, a Sikh temple in PD1," it said in a tweet.
Sikh lawmaker Nardendar Singh Khalisa told reporters close to the scene that up to 150 people were praying inside the gurdwara when it came under attack.
