"In a bomb explosion which targeted the bus of Iranian pilgrims, seven Iranians were injured," Shahsavari told the Mehr News Agency on Sunday
The bombing, which targeted Iranian pilgrims, was just one of the terrorist attacks occurred in Iraq on Sunday.
According to AP, a flurry of morning bombs killed 10 people and wounded 34 around Baghdad on Sunday.
The report quotes an Iraqi intelligence official as saying the attacks were trying to present the country as dangerous because Arab heads of state and their large retinues plan to meet in Baghdad in late March for the annual Arab League summit.
Every day hundreds of Iranians visit the holy shrines in Iraq and it is not the first time that Iranian pilgrims have come under attacks by terrorists who seek to create religious division and undermine security in the war-ton country.
In November nine Iranian pilgrims were killed and many more injured in two terrorist bomb attacks in Iraq's holy cities of Karbala and Najaf.
