At least 33 people were reported killed in a powerful explosion that rocked central New Delhi on Saturday, television reports said. Minutes later, two other explosions shook the city, officials said.
At least 40 people were hospitalized after the first explosion, in the crowded Paharganj neighborhood of the Indian capital, New Delhi Television said.
Vir Singh, a spokesman for the city's fire department, confirmed that there also had been explosions near the main market in Sarojini Nagar, a crowded south New Delhi neighborhood, and on a bus in the Govindpuri neighborhood.
He had no further details.
The first blast took place in the main Paharganj market in the evening, when it was filled with shoppers ahead of a major Hindu festival next week, the fire brigade said.
Paharganj is a busy wholesale market, dotted with small, inexpensive hotels frequented by foreign travelers, particularly backpackers.
All roads to the scene of the explosion were sealed off by authorities.
