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.
