Bangladesh has dismissed reports in the Indian media that explosives used in the Mumbai blasts came from Bangladesh.
Bangladesh has denounced all forms of terrorism
Home Minister Lutfozzaman Babor told reporters in Dhaka that the allegations were "ridiculous and laughable".
Officials say security has been further increased in Bangladesh since the blasts in Mumbai (Bombay) which have been unreservedly condemned by Dhaka.
Mr Babor said that bombings last year in Bangladesh were carried out by militants using explosives from India.
He said that the allegations in the Indian media could have been made "to counter" this fact.
The minister said the Jamaat-ul Mujahideen Bangladesh (JMB) group used explosives of Indian origin, which were smuggled into the country.
More than 30 people were killed in a series of nationwide bomb attacks 17 August 2005, allegedly carried out by the banned Islamic group.
Most senior JMB figures were arrested, and have been sentenced to death.
Officials said security had been increased across Bangladesh following the Mumbai bombings.
In addition to denouncing the Mumbai bombings, Dhaka maintains that it has always stood against terrorism "in all forms and manifestations".
