The two women arrested in connection with Burdwan accidental explosion have revealed that they were planning to blow up Kolkata airport and 24 other places in West Bengal on the festive day of Eid al-Adha.

On Monday, the Muslim community in Bengal peacefully celebrated their festival, which would have otherwise been disrupted with blasts all over the state if the accidental explosion hadn't taken place in militants' rented house in Khagragarh area.

While the plan fell through this time, two of their members, who had delivered four consignments of Improvised explosive device (IED), are at large, which might pose a threat to the nation, Hindustan Times reported.

During interrogation, the two arrested women, Amina Bibi and Rajira Bibi, told India's Crime Investigation Department (CID) that one of the two men is an important link between terror outfit Jamaat-ul-Mujahideen's head in Bangladesh and its other networks.

The women told the CID that Kausar, who collected a parcel containing IED on 1 October, knows how to channelize the bomb into explosion, which proves to be of greater threat to India.

Kausar also knows about the terror group's network spread across both the nations, which has triggered a massive search for him and his other companion.

"He is crucial to the investigation as he has wide information about the group in India. Railway police and BSF have been alerted in this regard," a CID officer, preferring to remain unnamed, said.

Kausar and his companion have delivered four IED consignments for the past three months and police of either side have not been able to trace them yet.

While the two women survived the blast at their house along with Hasan Saheb, who has suffered injuries and is undergoing treatment in Burdwan Medical College and Hospital, other members Shakil Ahmed and Sovan Mandal died in the explosion.
