Talking to reporters on the sidelines of a function here, Ramachandran said the government was monitoring the activities of some organisations and individuals in Kerala, who allegedly have close links with extremist forces.
"If you ask me whether there is any organisation with terrorist link in Kerala, then I cannot say no," he said. The probe by Maharashtra ATS and Central agencies into the blasts was progressing, he said.
The triple blasts at Zaveri Bazar, Opera House and Dadar had left more than 130 people injured.
