The bomb blast aftermath
At least 60 people have been killed and more than 150 wounded after a series of bomb blasts tore through the city of Jaipur in western India, officials say.
The bombs went off near historic monuments in the crowded old city at one of the busiest times of the day.
The head of state police said it was a terrorist attack. Reports suggest the death toll could rise.
Jaipur, in Rajasthan, is a popular tourist destination about 260km (160 miles) from the Indian capital, Delhi.
No group has admitted planting bombs in Jaipur. It is not yet clear what the motive for attacking the city might be.
Most people in Jaipur are Hindus but the city has a large Muslim minority. Correspondents say it has no history of religious violence.
There have been sporadic bomb attacks around India in recent years. The police have had little success in bringing prosecutions.
Up to seven blasts were heard in the heart of Jaipur, capital of Rajasthan state, starting at around 1915 local time (1345 GMT).
Each came a few minutes apart and eyewitnesses spoke of panic and then a stampede in the crowded old walled city.
Television pictures showed scenes of twisted debris and pools of blood on the streets.

One exploded close to Jaipur's most famous landmark, the historic Hawa Mahal, or palace of winds.
"It's a terror attack. There was no [intelligence] report of this," police director general AS Gill told reporters.
"The way it has been done, the attempt was to cause the maximum damage to human life," he added.

Jaipur is an extremely popular stop on India's primary tourist circuit known as "The Golden Triangle", which takes in other historic sites of Rajasthan and the Taj Mahal in Uttar Pradesh state.
It is known as the Pink City, for the colour of its forts, palaces and city walls.
