Huzaifa Afnan, who was critically injured by gunfire fired from across the Myanmar border in Teknaf, died at a hospital in the capital on Saturday morning after 27 days of treatment.
Huzaifa breathed her last around 9:45am at the National Institute of Neurosciences and Hospital in Dhaka, her family members said.
Her uncle Shawkat Ali said doctors declared Huzaifa dead in the morning.
Preparations are underway to take her body back home, he said.
Huzaifa, 13, daughter of local resident Jasim Uddin, was critically wounded on January 11 when bullets fired from the Myanmar side hit her at the Techchhi Bridge area of Hwaikyang in Teknaf of Cox’s Bazar.
She was initially given treatment locally.
As her condition deteriorated, she was admitted to the Intensive Care Unit (ICU) of Chattogram Medical College Hospital the same day.
Two days later, on January 13, Huzaifa was shifted to Dhaka for advanced treatment as doctors were unable to remove the bullet lodged in her head.
Professor Harun-or-Rashid, head of the Anesthesia and ICU Department at Chattogram Medical College Hospital, had earlier told the media that although surgery was performed the bullet that penetrated her brain could not be removed due to high risk.
“Efforts were made to reduce pressure on the brain,” he said at the time.
The incident had sparked concern among local residents over border security and cross-border firing in the Teknaf region.
