A U.S. air base in western Germany received a bomb threat on Monday evening, prompting a large operation by local police and American forces to secure the site, police said on Tuesday.

Police in the western state of Rhineland-Palatinate said the base had received a call from a man who spoke in German with a Russian or Turkish accent and threatened to attack the air base in Spangdahlem with bombs. He had at least four accomplices.

"After the telephone threat, the American forces informed the police, who moved swiftly with U.S. security forces to protect the air base," the police said in a statement.

The threat came a day before the sixth anniversary of the Sept. 11 attacks on the United States and roughly a week after German authorities say they prevented major bomb attacks on U.S. sites in Germany by a domestic cell of Islamist militants.
