BERLIN — ****** evacuated part of a terminal at Germany’s biggest airport this morning over concerns that at least one person might have gotten through the facility’s security area without being screened.

Federal ****** stopped boarding flights in area A of Frankfurt Airport’s Terminal 1 around midday and cleared the security area. The precautions were lifted about two hours later.

****** spokeswoman Julia Thiel told The Associated Press that “there were indications that at least one person” entered a secure area without being checked so the area had to be cleared.

It wasn’t immediately known how many people were affected.

****** tweeted after about two hours that “the affected areas are open and operations are in progress again.”

****** later said on Twitter that the midday ********** was prompted by a security assistant mistakenly allowing the French family of four into the secure area even though they were supposed to be subject to a secondary screening.
