Jaipur (PTI): Rajasthan Chief Minister has condemned the serial blasts in the pink city which claimed at least 60 lives and said that it was a well designed conspiracy by the terrorists outfit to disturb the peaceful atmosphere in the state.

Addressing a press conference, Raje said: "never in the history of the state such a heinous incident had happened and this is not an attack on the state but on the nation."

She asked all the political parties to come together and face the crisis.

Appealing to the people to maintain peace, she said that section 144 has been promulgated in the city and police vigil has been intensified.

She said investigation was going on and reports is expected tomorrow which would specify who were behind this heinous crime.

Raje also announced a state mourning today and said: "all government offices, schools and colleges will be closed for a day as a mark of respect for all those killed in the serial blasts in the pink city."
