The Union Home Minister, Mr. P. Chidambaram said that the Varanasi blast was the failure of the State Government intelligence agencies as the Centre has given a specific advisory two times to the States about Varanasi terror strike. Talking to media persons at Varanasi this afternoon, he said, 31 persons are admitted in different hospitals and he would discuss with the state government about their best treatment. He expressed the hope that the State security forces would be capable to book the culprits of the blast but, if requested, the Centre may ask the National Investigation Agency to investigate the incident. Mr. Chidambaram said that the Centre is ready to provide all types of help to the State about investigation of the blast and the treatment of the injured.
