WASHINGTON: The Trump administration on Wednesday strongly condemned the "cowardly" terror attack on Amarnath pilgrims in Kashmir and vowed that the US and India will together continue to fight terror threats in "every part of the world".

Seven Amarnath pilgrims were killed and 19 others injured in the terrorist attack in south Kashmir's Anantnag district on Monday night.

"The United States and India will continue to fight together against terrorist threats in every part of the world," White House Press Secretary Sean Spicer said in a statement issued two days after the attack.

The United States "strongly condemns the cowardly terrorist attack" on religious pilgrims in the state of Jammu and Kashmir on July 10, he said.

"We extend condolences to the victims' families and the people of India. An attack on religious freedom is an attack on the most fundamental right of liberty," Spicer said.

Earlier, State Department Spokesperson Heather Nauert had expressed concern over the terror attack.

"We consider it to have been a terrorist attack in the state of Jammu and Kashmir in which seven religious pilgrims were killed. That's of great concern to us," she told reporters at a news conference.

"These were civilians, they were killed as they were exercising their right to worship and that is, in large part, what makes this so reprehensible. That is a great concern to us and our thoughts and prayers go out to those people and to their families as well. Our prayers are with the victims and those who were affected," she said.

Several US lawmakers also condemned the dastardly act.

Congressman Will Hurd condemned the attack, saying, "My thoughts and prayers to all of the Amarnath Yatra terror attack victims and their families. The attack is reprehensible and must be condemned."
