Rattling sabers at new Iranian base at Afghan border.

Iran has inaugurated a new air force base in Birjand, close to its eastern border with Afghanistan. The new Ghaem al Mohammad air base is reportedly equipped with the latest generation radar system and will play host to a squadron of Iranian fighter jets.

"This base will serve to respond to any attempt by the enemy to attack the Islamic republic," said General Ahmad Mighani. "Our enemies must know that if they attempt to attack our country, we will teach them a lesson they will never forget," he said.
