The United State President Donald Trump and other leaders from Russia, Ukraine, Israel, Iran, France, Italy and the United Arab Emirates has condemned the Tuesday attack that killed 26 people, leaving 17 injured in Kashmir Indian.

Trump denounced the attack and expressed solidarity “with India against terrorism” and called Modi to convey his sympathies, according to Indian authorities.

Tourists were killed, while some injured after gunmen opened fire on a group in Indian-controlled Kashmir, the worst assault in years targeting civilians in the restive region that has seen an anti-India rebellion for more than three decades.

Tuesday’s attack took place in the picturesque town of Pahalgam in the Himalayan Mountains, popular with Indian visitors.

The attack came as U.S. vice-president JD Vance was on a sightseeing trip to the Indian city of Jaipur on Tuesday, a day after meeting with Modi in New Delhi.

Vance also condemned the killings, saying: “Over the past few days, we have been overcome with the beauty of this country and its people. Our thoughts and prayers are with them as they mourn this horrific attack.”

He will be in the Indian city of Agra on Wednesday to visit the iconic Taj Mahal monument, which is some 1,000 kilometres (621 miles) away from the attack site.

Police accused rebels of masterminding the attack, which sparked outrage and drew international condemnation.

The attack on Tuesday hasn’t been claimed by any group so far, and on Wednesday, Indian soldiers were still searching for the attackers.

Many fear the tourism industry, which employs thousands of people, will be negatively affected.

This also comes as Prime Minister Narendra Modi is soon expected to inaugurate a multibillion-dollar railway line to Kashmir Valley, which his government says will help tourism and economic development in the region.

Modi has decried the “heinous act” and pledged the militants“will be brought to justice.”

India’s powerful home minister, Amit Shah, visited the attack site on Wednesday.

Militants had attacked civilians before, but the last major attack was in 2000. And though the regionhas seen a spate of targeted killings in remote mountains in recent years, violence has largely declined in the Kashmir Valley, the heart of anti-India rebellion.

Indian tourism has flourished in Kashmir after the Modi government promoted visits to the region with the hope of showing rising tourism numbers as a sign of renewed stability there, albeit under heavy security presence, checkpoints, armored vehicles and patrolling soldiers.
