(VOVworld) – The Islamic State (IS) posted photos and slogans online, calling on Muslims in Germany to carry out Brussels-style attacks on Chancellor Angela Merkel’s Office and the Cologne-Bonn airport.

The intelligence group Search for International Terrorist Entities (SITE), which monitors Muslim websites, said all five photos posted on social media on Wednesday contain the logo of Furat Media, an IS affiliate. These photos and graphics include slogans in German urging Muslims to carry out attacks against the "enemy of Allah."

German media published a video about the attacks in Brussels, including three seconds shot at Frankfurt airport, apparently taken from German television news footage.

The Federal Criminal Police (BKA), who track suspected militants with German passports returning from battles in Syria and Iraq, said they already knew about the photos and the video, and that current security measures are adequate.
