Tehran: The wives of two Iranian military chiefs were among 10 killed on Wednesday in a bomb attack on a military parade in the northwestern Kurdish town of Mahabad, a senior official told Mehr news agency.
"The bomb exploded 50 metres from the parade stand and killed 10 people including the wives of two senior military commanders of Mahabad," Provincial Governor Vahid Jalalzadeh told the agency.
He added that 20 people had been injured, with "four in critical condition."
Jalalzadeh had earlier told the official IRNA news agency that nine people died in the attack, most of them women and children.
The attack took place as Iran marked the 30th anniversary of the start of the eight-year Iran-Iraq war with a series of army parades across the country.
Western Iran, which has a sizeable Kurdish population, has seen deadly clashes in recent years between the Iranian security forces and Kurdish rebel groups, mainly the Party of Free Life of Kurdistan (PJAK) operating from bases in neighbouring Iraq.
