The deceased were identified as Junayed, 10, son of Siddiqur Rahman, and Yeasin, 9, son of Russell Hossain, both hailing from Patakata village under the Baaliatali union of the upazila.
Locals said the children were playing on the bank of the pond beside their house in the afternoon. Accidently Junayed fell into the water body while Yeasin jumped into it to save him.
As they were not found for long despite searching, later their bodies were found floating in the water body, they said.
Though they were immediately rushed to Barguna General Hospital where physicians declared them dead upon arrival, said Dr Tajkia Siddika, resident medical officer of the hospital, reports UNB.
Later, the bodies were handed over to the families upon primary examination, she added.
