A passenger bus in Dholaipar, Dhaka, was set on fire by unidentified miscreants on Wednesday evening, according to the Fire Service. Two units from the Postogola station quickly responded and extinguished the blaze, preventing casualties. The cause of the fire remains under investigation. The incident follows a series of similar attacks and explosions across the capital, including vehicle fires in Ramna, Uttara, Mirpur, and Mohammadpur since Tuesday night. Police attributed some earlier fires to mechanical faults, though several remain unexplained. Authorities are on alert as incidents involving petrol bombs and crude explosives have injured security personnel and damaged vehicles in multiple areas.
