SRINAGAR, India—Suspected rebels using guns and grenades sneaked into a crucial army base in Indian-controlled Kashmir early Sunday and killed at least 17 soldiers in the deadliest attack on a military base in the disputed Himalayan region in recent years, the army said.
Four rebels were killed as the soldiers returned gunfire after the surprise assault before dawn on the base, located near the highly militarized Line of Control dividing Kashmir between India and Pakistan.
Loud explosions were heard and several barracks caught fire in the initial hours of the attack. Afterward, military helicopters hovered over the base as the army conducted what it described as “mopping up” operations.
Officials said at least 30 soldiers were wounded in the attack, including about a dozen who were in critical condition.
The casualties were high because a large number of soldiers were turning over the base to new units and were stationed in tents and temporary shelters that caught fire in the attack, the army said in a statement. The base, located in the town of Uri, west of the region’s main city of Srinagar, houses the Indian army’s regional brigade headquarters along the de facto border separating Indian- and Pakistani-controlled Kashmir.
Soldiers were conducting searches in the area, but army officials said it appeared that they had killed all four rebels involved in the attack.
Army officials said the rebels had infiltrated into the Indian side of Kashmir from the Pakistani-controlled part.
Lt. Gen. Ranbir Singh, the army’s director general of military operations, said that all four gunmen killed were “foreign terrorists,” and that initial investigations suggested that they belonged to Jaish-e-Mohammed, a militant group that has been active in Kashmir for more than 15 years.
India blames the outlawed group, which is based in Pakistan, for a series of attacks in the Himalayan region and Indian cities, including the attack on India’s Parliament in 2001 that brought nuclear rivals India and Pakistan to the brink of war.
Singh said the gunmen were carrying “some items that had Pakistani markings.” He said he had spoken to his Pakistani counterpart and conveyed India’s “serious concerns.”
The army officials said the rebels entered the sprawling camp after crossing a stream and breaching the fencing Saturday night.
What made Sunday’s attack different from earlier attacks in the region was that instead of storming into the camp, the rebels quietly entered the base and later launched their attack, said a senior army officer who spoke on condition of anonymity because he was not authorized to speak to reporters.
Indian Prime Minister Narendra Modi condemned the attack and tweeted, “I assure the nation that those behind this despicable attack will not go unpunished.”
Indian Home Minister Rajnath Singh called an emergency meeting of top defense officials and blamed Pakistan for the attack. “I am deeply disappointed with Pakistan’s continued and direct support to terrorism and terrorist groups,” he tweeted.
Pakistan’s army said in a statement that the allegations were “unfounded and premature,” reiterating Islamabad’s stance that no infiltration is allowed from Pakistani soil.
Kashmir is divided between India and Pakistan, but is claimed by both in its entirety. Most people in the Indian-controlled portion favor independence or a merger with Pakistan. A militant uprising and subsequent army crackdown since 1989 have killed more than 68,000 people.
India accuses Pakistan of training the militants in its territory, then helping them to infiltrate into the Indian side. Islamabad denies the charge, saying it only gives political and diplomatic support to the rebels.
U.S. State Department spokesman John Kirby said the United States “strongly” condemns the attack. “The United States is committed to our strong partnership with the Indian government to combat terrorism,” he said in a statement.
The attack came with Kashmir in the midst of its largest anti-India protests against Indian rule in recent years, sparked by the July 8 killing of a popular rebel commander by Indian troops. A sweeping military crackdown and near-constant curfew have been in effect since the protests began.
Rock-throwing protesters have clashed with troops firing live ammunition and shotgun pellets, and more than 80 people have been killed in the violence.
Amid the protests, India’s military has had to halt its operations against militants because Kashmiri civilians have hurled rocks at the troops trying to go after the rebels in neighborhoods. However, several suspected militants have been killed along the de facto border.
The last major attack on an Indian military installation was in January, when six gunmen entered an air force base in the town of Pathankot in the state of Punjab. The rebels managed to paralyze the massive base for nearly four days, killing seven soldiers. That base also is close to India’s border with Pakistan.
