Sixty people were killed in a series of bomb attacks in India's western city of Jaipur tonight, police said.
At least six bombs, which exploded in markets and near a Hindu temple in Jaipur's crowded walled city just as many people took to the streets after a hot day, also wounded up to 150 people, officials said. Some of the bombs were attached to bikes.
Rajasthan state government officials said between 50 and 60 people were killed in the explosions, the deadliest bomb attacks in India in nearly two years.
No group has claimed responsibility for the attacks, but India has previously blamed Pakistan-based Islamist militants fighting to end New Delhi's rule of Kashmir for such bombings.
Television channels quoted government and intelligence officials as blaming Pakistani or Bangladeshi Islamist militant groups.
In July 2006, seven explosions ripped through Mumbai's railway system killing more than 180 people. That attack, like many others, was blamed on Islamic militants based in neighbouring Pakistan and aided by local Muslims.
Prime Minister Manmohan Singh condemned the bombings and appealed for calm.
Police said high explosives were used in the bombs, with a range of around 50 feet (15 metres) in radius.
One blast was near a Hindu temple, where large crowds gather every Tuesday in honour of the monkey God Hanuman.
The latest attack comes just over a week before India's foreign minister, Pranab Mukherjee, is due to visit Islamabad to review the four-year-old peace process, his first visit since a new, civilian government took over in Pakistan.
