Defense Minister Annegret Kramp-Karrenbauer - also the leader of Chancellor Angela Merkel's Christian Democrats (CDU) said the security zone should involve Turkey and Russia. She wants it to protect displaced civilians and ensure the fight continues against Islamic State militia, the first time Berlin has proposed a military mission in the Middle East.
"Since yesterday, after the CDU leaders' proposal, we have got some questions from our allies and there is some - this is indisputable - irritation amongst our partners," Maas said, adding there was currently no discussion among partners about creating such an international security zone.
