The United States designated a Muslim militant group a "foreign terrorist organization" over an attack on Indian tourists in the Kashmir region in April in which 26 people were killed, saying the organization was a front for Pakistan-based Islamists who have been battling Indian forces in the disputed Himalayan region for decades.

The United States on Thursday designated as terrorists a shadowy group blamed for an April attack in India-administered Kashmir, which triggered the worst conflict between India and Pakistan in decades.

The US has designated The Resistance Front, which initially claimed responsibility for the deadly attacks in Kashmir, as a terrorist organization, marking a diplomatic victory for India.
