There are some "slender leads" on which the state agencies are working and it is difficult to name any terror outfit at present, she told a press conference in Jaipur.

While no one has yet been arrested, some people have been detained for interrogation, the chief minister said in a second press meet since the blasts, but did not give out the number of those being questioned.

So far 63 people have died -- 56 in SMS hospital and 7 in SDM hospital, she said, adding that the dead included several women and children. The number of those who sustained injuries in the blasts is 118, she said.

Raje said 44 bodies have been identified and handed over to the relatives.

Replying to questions, the Chief Minister said there was no specific information with regard to the terror strike from central agencies except some regular notices sent on Republic and Independence days to every state.

Earlier, Prime Minisiter Manmohan Singh and Union Home Minister Shivraj Patil spoke to Raje on phone and assured all possible help from the Centre in the wake of the terror strike. Observing that the blasts were part of a terrorist design to disturb peace in the state, Raje said, "never in the history of Rajasthan such a heinous incident has happened and this is not an attack on the state but on the nation."

She also stressed the need for an anti-terror law like POTA. "I am not playing politics on the issue but we require central-state cooperation to work against global terror", Raje said.
