U.S. military bases placed on high alert

Several US military bases across Europe have been placed on heightened alert, with the Pentagon citing the risk of terror attacks. Trent Murray reports from Berlin.

According to CNN, it is not clear what intelligence triggered the heightened security, but European authorities have warned of a potential terror threat on the continent, especially ahead of the Paris Olympics in July and during the current European football championships in Germany.

The German government brought in 580 international police officers to assist with security alongside German officers.

Interior Minister Nancy Faeser said ahead of the tournament, “We are preparing ourselves for all conceivable dangers: from Islamist terror to violent criminals and hooligans.”
