"However, we will not pinpoint definite organizations responsible as the investigations are still in a preliminary stage," Shinde told reporters after presiding over a high level meeting to chalk out disaster management plan in the wake of the train blast in Mumbai.

Rejecting failure on part of intelligence agencies to avert the tragedy, the chief minister said, "We had definite information that something may happen after Aug. 15 last year."

He said that ammonium nitrate was used in the "clandestinely made" device used for triggering the blast in the train Thursday night at Mulund station on the central railway.

He linked the Mulund blast to the explosion that had occurred in a bus in Ghatkopar in Mumbai on Dec. 2, last year, in which two persons were killed.

However, the intensity of the blasts in the recent past including that of Thursday's was low compared to the 1993 serial blasts that had rocked the metropolis, he said.

He said that these explosions were aimed at creating fear psychosis among the public and he asked people to be on constant vigil and alert.

On March 12, 1993, 13 explosions shattered the city of Mumbai, killing 257 people and injuring 713 others.
