SRINAGAR: India’s anti-terrorism agency on Monday charged militant Islamist groups based in Pakistan and six individuals over an April attack on tourists in Indian-administered Kashmir that killed 26 men, and triggered intense fighting between the two countries.

The fighting, the worst between the nuclear-armed neighbors in decades, was sparked when militants opened fire on Hindu tourists in the Pahalgam region of Kashmir. New Delhi said the attack was backed by Pakistan, allegations which Islamabad has denied.

Pakistan-based Lashkar-e-Taiba (LeT) and its offshoot The Resistance Front (TRF) were charged for their alleged role in “planning, facilitating, and executing the Pahalgam attack,” according to a statement from India’s anti-terrorism agency.

Three men killed by Indian security forces during Operation Mahadev in July in Srinagar, who were claimed to be Pakistani nationals, were charged posthumously, according to the statement. Another two men already in custody were charged, and a man accused of being a Pakistani terrorist handler.

A spokesperson for Pakistan’s foreign ministry did not immediately respond to a Reuters request for comment.
