At least six Iranian pilgrims have been injured in two separate bomb attacks which targeted the pilgrims' buses in the Sa'adun region in the Iraqi capital, Baghdad, Press TV reported.
The first bomb hit a bus early Tuesday, moments after it left a hotel in the Sa'adun area to head to the holy city of Karbala, 100 km southwest of Baghdad.
According to the representative of Iran's Haj and Pilgrimage Organization, Javad Khani, the incident left four pilgrims injured.
The second bomb went off in another location in Sa'adun when the pilgrims were boarding another bus, injuring two more Iranian pilgrims, IRIB reported.
"Four Iranians were injured in the first explosion, while the second blast left two others wounded," IRIB quoted Khani as saying.
This is while an Iraqi interior ministry official put the number of the wounded Iranians at 12. According to the Iraqi official, three members of a police officer's family were also injured in the bomb attacks.
The Iranian pilgrims had visited the cities of Samarra and Kazemein and were scheduled to depart Sa'adun for Karbala on Tuesday morning, Khani reiterated.
Earlier last week, seven other Iranian pilgrims were wounded in an explosion in the Iraqi town of al-Muqdadiyah, northeast of the capital, Baghdad.
Iraq has been suffering attacks on an almost daily basis in the chaos that followed the US-led invasion of the country in 2003.
