Iranian state TV is reporting that the country will begin large-scale air defense war games Sunday aimed at protecting nuclear facilities against any possible attack. Gen. Ahmad Mighani, who heads an air force unit dealing with threats to Iran's air space, says the war games will cover regions where Iran's nuclear facilities are located, according to the report. The official IRNA news agency says the drill will cover 230,000 square miles (600,000 square kilometers) in central, western and southern Iran.
