"A team of NIA is reaching the Bangalore blast site. We are in constant touch with the Karnataka government and ready to offer any help which is required," Minister of State for Home RPN Singh told reporters here.
Singh said the nature of the blast and the materials used to carry out the explosion were not so far clear and investigators were looking into all possibilities as nothing can be ruled out.
The Minister appealed to everyone to maintain peace and not to indulge in rumour mongering.
Referring to Monday's blasts in US city of Boston, Singh said terrorism was a global phenomena and everyone should be united to fight the menace.
The Minister said all political parties should join hands and work for the interest and integrity of the country.
