The incident took place around 5:30 pm at Bailab village in Chakradha union.
The victims were Oliul Islam Sohag, 40, and Sazzad Hossain Rana, 35, sons of retired army personnel Asaduzzaman Montu.
Their mother, Shamima Akter, was also seriously injured.
According to police and local sources, the dispute started over water from a tubewell used by Didar and Bidyut, which flowed into Sohag’s land.
On Wednesday, the argument escalated when uncle Mamun and his sons attacked the two brothers with knives, sticks, and rods.
Rana died on the spot from stab wounds.
Sohag was rushed to Shibpur Upazila Health Complex where doctors declared him dead, reports UNB.
Shamima Akter, the grieving mother of Sohag and Rana, said, “Their tubewell water comes into our land, making it hard for us to move around. My younger son Rana told his uncle about it, and Mamun with his sons attacked him with knives. When my elder son Sohag ran to help, they hit him with sticks and stabbed him until he fell. I want justice for my sons.”
Officer-in-Charge of Shibpur Model Police Station, Afzal Hossain, confirmed the incident.
“The killings happened due to a long-running family feud. Both bodies have been sent to Narsingdi Sadar Hospital morgue for autopsy. No arrests have been made yet. Investigation is ongoing, and legal action will follow”, he added.
