At least 51 people, including Gopalganj-1 MP Salimuzzaman Salim, were injured in a multi-vehicle collision involving around 20 vehicles in Gopalganj on Friday.
The accident occurred in the Boraitala area of the Dhaka-Barisal highway in the morning.
According to eyewitnesses and police, the MP was on his way to attend a protest meeting in Boraitala when a passenger bus operated by Dolphin Paribahan slammed into the rear of a truck carrying paddy.
The impact caused the truck to lose control and hit vehicles ahead, triggering a chain collision involving 15 to 20 vehicles.
The rear of the private car carrying the MP was badly crushed. Several other vehicles in his convoy, along with passenger buses, easybikes and motorcycles, were also damaged.
Rescuers took the injured to Muksudpur Upazila Health Complex and nearby clinics, where they received treatment.
Traffic on the Dhaka-Barisal highway remained suspended for nearly an hour following the accident.
Later, Bhanga Highway Police removed the damaged vehicles from the road, allowing traffic to return to normal.
