Police sources said that 75 persons perished in the attack that triggered a stampede in the affected areas in the walled city which are frequented by foreign tourists. Six women were among the dead.

It is for the first time that the Pink City is coming under terror radar.

Scores of wounded people were ferried to several hospitals soon after the low-intensity blasts hit at Tripolia Bazar, where large number of devotees turned up at a Hanuman temple, Johari Bazar, Manas Chowk, Badi Choupal and Choti Choupal in the walled part of the city.

Rajasthan Director General of Police A S Gill said it was 'obviously a terror attack'. Police sources said the attack was meticulously planned and the first blast occurred around 7.40 pm and the remaining blasts were set off in quick succession.

The Union Home Ministry reviewed the situation while Mumbai and Delhi were put on high alert.

Rapid Action Force (RAF) personnel were deployed in Jaipur to help deal with the situation as security was beefed up.

One of the blasts took place in a car and another near a handloom shop in Kotwali area of the city, Home Department sources said.

The injured were rushed to Sawai Man Singh hospital, the sources said.

The blasts triggered a near-stampede situation at the blast sites crammed with peak-hour shoppers as panic-stricken people ran helter skelter in search of a safe place.

The Hanuman temple at Tripolia bazar was crowded with worshippers being a Tuesday.

There were also reports that a live bomb was defused by a bomb disposal squad.

Police sources said that cycles may have been used to trigger the blasts that occurred in the space of 12 minutes at the crowded areas.
