Germany's Frank-Walter Steinmeier used his first speech as president on Wednesday to warn his Turkish counterpart Recep Tayyip Erdogan that he risked destroying everything his country had achieved in recent years.
"The way we look (at Turkey) is characterized by worry, that everything that has been built up over years and decades is collapsing," Reuters cited Steinmeier as saying.
"President Erdogan, you are jeopardizing everything that you, with others, have built," he said, adding that he would welcome "credible signs" to ease the situation.
"End the unspeakable Nazi comparisons! Do not cut the ties to those people who want partnership with Turkey! Respect the rule of law and the freedom of media and journalists! And release Deniz Yucel," he urged.
