The tribunal in Dhaka delivered a verdict Wednesday on nearly 50 cases stemming from the grenade attack 14 years ago that killed two dozen people and wounded hundreds.

Two former Cabinet ministers were condemned to death. Jailed former Prime Minister Khaleda Zia's son Tarique Rahman received a life sentence. Eleven defendants were given six months to two years in prison.

Rahman's conviction on conspiracy charges related to the 2004 attack could keep Hasina in power in elections due in December. Hasina narrowly escaped the attack.

Zia is jailed for corruption and Rahman, her heir-apparent, lives in London.
