NEW DELHI: Everyone at the Indian consulate in Afghan city of Mazar-i-Sharif , which came under attack by unidentified gunmen on Sunday night, is safe and security forces are clearing the area, India's ambassador to Afghanistan said."All well at consulate. Security forces clearing area around," Ambassador Amar Sinha tweeted."Heavy fighting is going on. Clearing operations by special forces are under way at Mazar-i-Sharif," the Indian envoy said.Assailants holed up in a building close to the consulate traded heavy fire with Afghan forces who cordoned off the street following a series of explosions, officials said.No group has so far claimed responsibility for the raid on the consulate in the northern Afghan city, the latest assault on an Indian installation in the country.The attack on the Indian consulate in Mazar-i-Sharif was yet another strike at Indian diplomatic missions in strife-torn Afghanistan over the past few years.The worst strike was a suicide bomb terror attack on the Indian embassy in capital Kabul on July 7, 2008, killing 58 people and injuring 141.The suicide car bombing took place near the gates of the embassy during morning hours when officials enter the mission building.On August 3, 2013, the Indian embassy in Jalalabad was attacked by three suicide bombers. The attack caused the deaths of nine Afghans with the majority of those killed being children.The Indian consulate in Herat, Afghanistan was attacked on May 23, 2014 by four heavily-armed militants. All the attackers were killed during a lengthy gun battle, one by the Indo-Tibetan Border Police (ITBP) and three by the Afghan security forces.
