Two three-year-old children drowned in rainwater accumulated in the elevator pit of an under-construction building in Tangail's Mirzapur yesterday.

Abdullah, son of Lal Miah, and Khadiza, daughter of Fazlul Karim, were playing outside their homes in Sohagpara area in the afternoon, family members said. 

The families didn't know something had happened to them until construction workers noticed their bodies floating in the water in the evening and informed them, said Abu Saleh Mohammad Masud Karim, officer-in-charge of Mirzapur Police Station.
