In the wake of the "terror" attack in Punjab, where three people were killed and 20 others injured in a grenade blast, Union Home Minister Rajnath Singh on Monday reviewed the security situation in the country.
Senior officials of the Home Ministry and security agencies briefed the Home Minister regarding the explosion at a religious gathering near Amritsar on Sunday, an incident which police are treating as a "terrorist act".
The Home Minister directed the officials to provide all assistance to the Punjab Government in their investigation to nab the perpetrators of the crime, a Home Ministry official said.
Singh was told that a team of the National Investigation Agency has already visited the blast site along with their investigators and explosive experts.
Three persons, including a preacher, were killed and 20 others injured when two-motorcycle borne men threw grenade on a religious congregation on the outskirts of Amritsar.
The incident took place inside the Nirankari Bhavan's prayer hall at Adliwal village near Amritsar's Rajasansi, police said.
A religious congregation of the Nirankari followers was being conducted inside the Bhavan at the time of the incident. The Sant Nirankari Mission is a spiritual organisation and the Bhavan lies close to the Amritsar international airport and the Indo-Pak border.
