The attack took place during the lunch time when dozens of passengers gathered in the restaurant, the source said.

Many of the victims were Iranian pilgrims who used to visit Iraqi Shiite holy sites in Iraq, the source added.

The blast destroyed parts of the restaurant and badly damaged several nearby civilian vehicles, he said.
