NEW DELHI -- A crude bomb blast took place in New Delhi in the early hours of Sunday morning, though no injuries were reported. Soon after the incident, the whole area was cordoned off, and investigating agencies were probing to ascertain the nature of the bomb.

A huge ball of white smoke was seen immediately after the blast, eyewitnesses were quoted as saying.

The blast took place near a school run by the paramilitary Central Reserve Police Force (CRPF) in New Delhi's Prashant Vihar residential area.

The strong bomb blast damaged the school's wall, nearby shops, and a car parked nearby. Window panes of nearby houses and shops were broken, spreading a wave of terror in nearby areas.

"It was around 7:45 when I was in my house, nearly 500 meters away from the spot of the blast. There was a huge sound. I was scared and ran out of my house. Later I gathered that a bomb blast had taken place near a school. There was white powder scattered at the spot of the blast," said a local resident Gulshan Narang.

Officers of several investigating agencies, the Central Forensic Science Laboratory (FSL), the Delhi Police and the Delhi Fire Services (DFS) reached the spot and investigated till the last reports came in.
