BAGHDAD, Iraq: A truck bomb struck the tomb of Imam-ol Asr (AS)’s fourth deputy on Tuesday in central Baghdad, leaving at least 82 people martyred and over 220 wounded.

The grave remained safe and secure.

The thunderous explosion at the Khulani tomb in the capital's busy commercial area of Sinak sent smoke billowing over concrete buildings, nearly a week after a bombing brought down the twin minarets of the holy Askariya shrine in the northern city of Samarra.

Authorities said that the toll could rise as bodies were pulled from the debris.

The mosque's imam, Sheik Saleh al-Haidari, said the explosion hit worshippers as they left afternoon prayers.
