Doctors at Dhaka Medical College Hospital (DMCH) amputated her legs, which were pulverised in the blasts. She was later shifted to the Combined Military Hospital (CMH).

The DMCH authorities said a three-hour operation was conducted on her and doctors were compelled to amputate her legs.

Sources at the DMCH said Ivy also had injuries to her chest and hands and her condition was critical. "She lost a good amount of blood that made her condition more vulnerable," said one doctor.

Some sources said the AL leader had another operation at the CMH at around midnight.

Witnesses said Ivy was close to the stage, the target of the attack. " She (Ivy) became one of the worst victims as the first bomb landed just 2/3 feet away from the stage," said one witness, Moni Akhtar, who is undergoing treatment at the DMCH.

"I was just two feet away from her (Ivy)," said Rani, a Mohila AL activist of Ward No 58. "The first bomb blast led to a chaos in the area and I saw bombs hurled from the ground level hit her when she tried to run away" she told a correspondent of The Daily Star.

"I crawled for a safer place and found her (Ivy) lying unconscious in a pool of blood," she added.
