One more child died from hornet stings in Dhobaura upazila of Mymensingh on Saturday night, taking the death toll from it to three.
The child was identified as Sifat Ullah, 5, son of late Maulana Abul Kashem, 55, an imam of Dudhnoi Bazar Mosque in the upazila.
Earlier on Sunday afternoon, the imam and his eight-year-old daughter Labiba also died from the hornet stings.
Family members and locals said a boat carrying Abul Kashem and his two children was passing by a bamboo bush on Saturday afternoon on their way to a local market. Suddenly they were invaded by hornets leaving them critically injured.
Locals rushed them to Dhobaura Upazila Health Complex, from where doctors referred them to Mymensingh Medical College Hospital.
However, both Abul Kashem and Labiba succumbed to their injuries on the way to the hospital. Though Sifat was admitted to Mymensingh Medical College Hospital, he also died around 10pm while undergoing treatment there.
Dhobaura Police Station's Officer-in-Charge Al Mamun Sarkar confirmed the deaths.
