Bangladesh's former prime minister Sheikh Hasina Wajed has gone deaf in her right ear after suffering an injury in a grenade attack at a rally last year, a media report said.

Hasina, who is undergoing treatment at a Florida hospital, told the Prothom Alo daily that she cannot hear with her right ear.

At least 23 people were killed and 300 others were injured in the attack at the August 21, 2004 Awami League rally in Dhaka.
