Three persons were killed and at least 10 injured in a grenade attack on a prayer hall, which had around 200 devotees, on the outskirts of the city on Sunday. The blast occurred during a religious gathering of the Nirankari sect at Nirankari Bhavan in Adliwal village near Amritsar's Rajasansi, which is close to the international airport. According to eyewitness accounts, bike-borne persons threw the grenade at the hall.

"Three people have died in the incident while 10 have been injured, two of them critically," Inspector General of Police S S Parmar, who visited the incident spot, said. Quoting eyewitness accounts, the IG said the two accused were carrying a pistol and after hurling the explosive, they escaped from the site. A hunt is on to nab them, he said.
