Tehran: Iran's army conducted exercises Tuesday close to its border with Afghanistan designed to simulate how it would respond if "terrorist groups" such as the Islamic State organisation mounted an attack.
The operation in the northeastern province of Khorasan came a day after a military commander said IS would be "neutralised" if it breached a 40 kilometre (25 mile) zone approaching Iran's borders.
Tanks, helicopters and planes took part in Tuesday's manoeuvres, the ISNA news agency reported.
The exercise followed IS attacks that killed 129 people in Paris last week.
"One aim of the exercise was to practice methods and means to confront the possible actions of terrorist groups at the borders," said General Amir Reza Azarban, an army commander in the province.
On Monday, General Ahmad Reza Pourdastan, the army's head of ground forces, announced the 40 kilometre limit on the borders with Iraq and Afghanistan, which if breached would trigger action.
