A rocket-launched grenade exploded inside a tennis court of the residential complex of Indian ambassador Manpreet Vohra in Kabul on Tuesday morning.
No injuries or casualties have been reported so far in the incident.
The attack has come at a time when the Afghanistan capital is hosting an international peace meeting called the Peace Process Conference. The meet is being attended by the representatives of at least 27 countries worldwide.
Meanwhile, Afghanistan President Ashraf Ghani on Tuesday announced that the death toll from a truck-bomb explosion on Kabul last week has reached more than 150. The attack is the deadliest in Kabul since Taliban's ouster in 2001.
The massive blast occurred when a sewage truck packed with what Ghani called "military-grade" explosives detonated at the entrance to a fortified area of that city that includes foreign embassies and government buildings.
"We were not the only targets, the entire diplomatic community was the target of this attack," Ghani told foreign diplomats gathered for the peace conference in Kabul.
Officials had put previous estimates of death toll from the attack at around 90. More than 460 people have been wounded in the incident.
Reports state that all those who were killed in the blast were Afghans. The Afghanistan President paid homage to 13 policemen who stopped the truck as it attempted to enter the fortified district. All the 13 policemen were killed in the explosion.
No extremist group has taken responsibility for the deadly attack yet.
