Several wounded in New York City blast

New York, Sep 18 

Several people have been wounded in an explosion in Manhattan, authorities said.

Fire trucks and ambulances converged on the scene after what witnesses described as a "deafening" blast in the Chelsea district of Manhattan around 9.00 p.m. on Sunday, BBC reported.

FBI and Homeland Security officials were at the scene, a local official told the US media.

The explosion comes just hours after a pipe bomb exploded in a New Jersey town, shortly before thousands of runners were to participate in a charity race nearby.

No injuries were reported in the New Jersey blast.
