responsibility for the attack so far.
The deafening explosion took place at around 10 am about 50 metres away from the consulate near a mosque, 120-km east of the Afghan capital of Kabul, provincial police chief Sharifullah Amin said.
Two of the attackers wearing vests laden with explosives got out of the car and were immediately fired upon by the police., he said.
"MEA (the minister of external affairs) is in touch with the officials. All officials are safe," tweeted Syed Akbaruddin, the spokesperson of the ministry of external affairs in New Delhi.
Afghanistan's main insurgent group, the Taliban, denied in a text message that it had carried out the attack. Smaller militant groups based in Pakistan have targeted Indian interests in Afghanistan in the past.
Hashimi said the attack began when three men in a car approached the checkpoint. Two of the men got out of the car wearing vests rigged with explosives and a police guard immediately opened fire on them, Hashimi said. He added that the third man then detonated a large bomb located inside the car.
India, which has spent more than two billion dollars of aid in Afghanistan since the Taliban regime fell in 2001, has been previously targeted in the war-torn country.
The attack came as the US planned to close its embassies in the Muslim world for the weekend due to an al Qaeda threat.
