An Iranian news agency says government forces have ambushed and killed several suspects of a bombing last week that killed 12 people.
The report from ISNA news agency quotes Gen. Mohammad Pakpour of the Revolutionary Guards saying the men were ambushed near the Iran-Iraq border on Saturday. It did not specify the number killed.
Pakpour, head of the Guards' ground forces, said Sunday the armed group was backed by Israel, the U.S. and members of the Iraqi Baath Party, former supporters of deposed leader Saddam Hussein.
An explosion during a military parade in the Iranian-Kurdish town of Mahabad killed 12 women and children on Wednesday.
No group has been officially named responsible, but it is an area where Kurdish separatists are active.
