Gunmen have reportedly attacked the Indian Consulate in the northern Afghan city of Mazar-e Sharif, attempting to enter the compound.
A spokesman for the regional governor said two explosions on January 3 were followed by gunfire outside the diplomatic mission.
An Indian consular official also confirmed the attack, telling the AFP news agency by telephone: "We are being attacked. Fighting is going on.”
No details were immediately available on casualties or damage.
Located about 400 kilometers north of Kabul, near the borders of Uzbekistan and Tajikistan, Mazar-e Sharif is a major hub for northern Afghanistan.
The attack came as Indian security forces continued their effort to repel an assault on an air base near the border with Pakistan.
At least seven military personnel have been killed and 20 others wounded.
