Iran warns IS against approaching its borders

A top Iranian army commander said on Monday that his troops would take "decisive" action if Islamic State group militants come within 40km of its borders with Iraq and Afghanistan.

The comments from General Ahmad Reza Pourdastan, who heads Iran's ground forces, came after Iraq's foreign minister said intelligence sources showed Iran was among countries IS had plans to attack.

"The Iraqi foreign ministry warned us but the Islamic Republic of Iran's army states that it has no fear of such threats and a red line has been drawn in Iraq 40km from the border," Pourdastan said.
