Two children were killed and four others injured in collision between a CNG-run autorickshaw and a locally made three-wheeler (votvoti) in Sherpur's Nakla upazila on Thursday evening.

The accident occurred around 7:30 pm in the Dhanakusha area on the Nakla-Nalitabari road.

The deceased were identified as 17-month-old Mujahidul Islam and Nahid Hasan, 15.

The injured include Mujahidul's parents, Monirul Islam, 30, and Nilufa Yasmin, 25, as well as Furkan Hamid, 30, and Jahanara Begum, 55.

According to police and local sources, Monirul was returning to his home in Phulpur with his wife and son in a CNG-run autorickshaw after attending a family gathering in Nalitabari. The autorickshaw collided with an oncoming votvoti in Dhanakusha village.

The impact threw Mujahidul, who was sitting on his mother's lap, onto the road, causing severe head injuries. He was taken to Nakla Upazila Health Complex, where the attending doctor declared him dead.

Another injured passenger, Nahid Hasan, was referred to Mymensingh Medical College Hospital but died on the way.

The remaining injured were treated at Nakla Upazila Health Complex.

Monirul Islam said he was returning home after visiting his sister's grandson when the accident occurred.

"After two daughters, Allah blessed me with a son. Now my only son is gone. Will I ever get justice?" he said tearfully.

Nakla Police Station Sub-Inspector Lokman Hossain said Mujahidul's body had been taken to the police station and an inquest report prepared.

Both the CNG-run autorickshaw and the votvoti have been seized, he added.
