More than a dozen CIA spies have reportedly been caught in Iran and Lebanon and the U.S. government now fears they have been executed. The spies were paid informants who were targeting Iran - which is feared to be producing nuclear weapons - and the Hezbollah group in Beirut. Their discovery is a big hindrance to U.S. attempts to track Iran’s nuclear activities and discover if Hezbollah is plotting any attacks against Israel. Past explosions: In 1983 more than 300 people - including 260 Americans - were killed in an attack on the U.S. embassy and Marine barracks in Beirut
