Vienna police said on Dec. 26 that a "friendly" intelligence service had warned European capitals of the possibility of a shooting or bomb attack before New Year, prompting police across the continent to increase security measures. 

The suspected mastermind of the Paris attacks was questioned by German police at Cologne-Bonn airport early last year before he boarded a plane to Istanbul, Spiegel magazine reported on Nov. 19, quoting security officials. 

Thousands of the around 200,000 Serbian citizens who sought asylum in Germany potentially face demands to leave the country and return to Serbia, the Belgrade-based daily Politika reported on Friday.

About 24,000 were already urged to leave Germany this year.
