Two workers, including a woman, were killed when a covered van hit them in Gazipur on Tuesday.
The deceased were identified as Rina Begum, 38, wife of Nasir Uddin of Sunamganj, and Mehedi Hasan, 45, son of Abdul Quader, former chairman of Jayashree Union of the same upazila.
Rina worked in an Ashulia factory in Dhaka and Mehedi Hasan in a company in Tongi.
