Three Iran guards killed in clash near Iraq border
The "border guards faced armed insurgents in a clash during their patrol, with some of the insurgents killed and three of the guards martyred," the news agency said.
The clash broke out near the town of Sardasht, it added, without naming the rebel group involved.
For much of the past 40 years, Iran has been battling Kurdish militants who use bases in neighbouring Iraqi Kurdistan to mount cross-border attacks against Iranian government targets.
