The NIA had in April 2020 registered a case in the March 25, 2020 terror attack. This was the first instance of the NIA filing a case for a terror attack committed outside India as per the amended NIA Act, which empowered the central agency to investigate terror attacks committed outside India "affecting Indian citizens or affecting the interest of India". The case was registered under various provisions of Indian Penal Code and anti-terror laws.

 

About 150 people were present in the gurdwara when the attack took place, and Indian citizen Tian Singh was also killed.

 

An NIA official said: "A team of NIA was yet to visit Kabul to carry on the probe. Looking at the current situation in Afghanistan, where the Taliban has captured power, the visit of NIA will be delayed to indefinite time."

 

According to NIA, Muhammed Muhsin, a 29-year-old from Kerala's Kasaragod district, was suspected to be one of the attackers. The Islamic State in Khorasan Province (ISKP) had claimed responsibility for the attack.

 

As per NIA officials, Muhsin went to the UAE in 2018 from where he is believed to have joined the ranks with the global terror organisation in Afghanistan.The official said that the anti-terror probe agency has collected DNA samples and spoke to nearly a dozen Sikh victims who were brought back to India in July last year.
