Three boys drowned in a water-filled pit in Sisneri, Makawanpur, on Monday.

According to the Makawanpur District Police Office, the incident took place near the Sisneri police post in Indrasarowar Rural Municipality-3. The boys drowned after they reportedly entered the pit to swim.

Police said the identities of the victims have not yet been confirmed, but they are estimated to be around 12 to 13 years old.

The pit was formed after a section of the road in Sisneri was washed away by heavy rainfall in September last year. The children entered into a deep water body formed of accumulated rainwater.

“Among the victims two had reportedly come to visit their relatives in Sisneri, while one child was from Sisneri itself,” Lalita Dhakal, chief of the area police office Bhimphedi, said.

The police are investigating the case further.
