Forces inimical to India's interests in Bangladesh, including the present government, were supporting the brains suspected to be behind the October 30 serial blasts in Assam, Chief Minister Tarun Gogoi claimed on Friday.

"The main brains or sources behind the blasts here are suspected to be based in Bangladesh. Forces inimical to India's interest are reponsible. The present Bangladesh government also," Gogoi told the media.

Asked why Bangladesh would create trouble in India, he replied, "they (the brains behind blasts) must be serving Bangladesh's interest. Otherwise why will they safeguard these people?”

"The Bangladesh part is being taken up with that government through the Government of India," he said.

The Chief Minister claimed that the ULFA, NDFB, KNLF all had bases in Bangladesh.

Stating that investigations into the serial blasts in the state which left 88 persons dead was progressing, he said, 15 NDFB and ULFA insurgents had been arrested for the explosions in Guwahati, Bongaigaon and Barpeta.

These persons were identified to be directly involved in the blasts, though the brains behind them were different, the Chief Minister said.

There was also evidence of an ULFA link in the Black Thursday blasts, he added.
