U.S. issues terror alert after alleged Iran plot is exposed
The U.S. State Department has issued a "worldwide travel alert" for Americans.
Officials say the alert is in response to a foiled terror plot to kill Saudi Arabia's ambassador to the United States. The State Department says the foiled scheme could be a sign that Iran has adopted a "more aggressive focus" on terrorist activity.
It says Iranian-sponsored attacks could include strikes in the United States, where the alleged plot against the Saudi envoy was supposed to have taken place, as well as other countries. AP wire services were used in this report.
