The Indian consulate in the northern Afghan city of Mazar-i-Sharif has come under attack as gunfire and rocket-propelled grenades rocked the surrounding area, Al Jazeera reported.
Two loud explosions and gunshots were heard earlier as the gunmen launched an attack from a nearby house, Muneer Ahmad Farhad, a spokesman for the Balkh province governor said.
Al Jazeera's Qais Azimy, reporting from Kabul, quoted police officials and said that four fully-armed gunmen had tried to enter the consulate.
"They faced resistance from the guards and, instead, entered a house about 100 metres from the consulate and opened fire from there," he said. "The house has been surrounded by the Afghan special forces."
Azimy added that some casualties had been reported but initial details were scarce.
Security forces are carrying out door-to-door search in the area and have not ruled out the presence of more attackers.
"It's not the first time an Indian diplomatic post has been attacked in Afghanistan. A couple of years ago, the Indian embassy in Kabul was attacked," Azimy added.
All Indian consular staff were safe, the Indian consul-general confirmed.
Sunday's attack came as Indian security forces were still trying to suppress an assault on an air base near the border with Pakistan that has killed at least seven military personnel and wounded 20 others.
