At least seven buses were set ablaze at different parts of Dhaka in Bangladesh on Thursday.

Reports say, leaders and workers of Jamat e Islam and BNP set the buses on fire alleging irregularities in the by-elections to Dhaka-18 and Sirajganj-1 constituencies.

Police said action will be taken against those involved in criminal activities.

Police said the incidents took place between 11 am and 3.30 pm at Shahbagh, Bongshal, Motijheel, Khilgaon, Paltan, Press Club and Pragati Sarani areas of Dhaka.

Later, the blaze was brought under control, sources said.

There was no report of injury in the fire incidents, said a police official.

DMP Deputy Commissioner (Media) Walid Hossain said: “Miscreants set fire on buses in different places of the city. The arson attacks might have link to Dhaka-18 by-elections.”

Two buses were set on fire at Motijheel, Secretariat Adjacent to the Press Club, in front of the Awami League’s central office on Bangabandhu Avenue and in the Shahbagh area between 1.30pm and 2.30pm.
