Two people were injured when a suspected crude bomb exploded on a busy road in the Indian capital New Delhi today, damaging vehicles and triggering a security alert, police said.
They said the explosion took place around 6.35 p.m. during the evening rush-hour traffic near the prestigious Indian Institute of Technology in south Delhi.
"It was a low-intensity explosion, probably an improvised explosive device. There are two minor injuries," Delhi's joint commissioner of police, told reporters.
"I do not think it is terrorist activity," he added. He did not give details.
The blast caused a small crater on the road and shattered glass panes of a bus and two cars.
Police said one of the injured was a bystander and the other was a scooterist passing by.
Armed policemen sealed off the scene of the blast, littered with shattered glass, and sniffer dogs were brought by forensic experts who began investigations.
Earlier, a witness contradicted the police version of events and said the blast was caused by an exploding compressed natural gas (CNG) cylinder that runs the bus.
But police said early investigations had ruled out a cylinder blast and said all cylinders on the bus were intact.
A security alert had been sounded in the capital, said another senior police officer.
Security is normally tight in New Delhi which has in the past been a favourite target of militants fighting against Indian rule in Kashmir and the northern state of Punjab.
