ANKARA, March 18 (Xinhua) -- Turkish presidential spokesperson Ibrahim Kalin on Saturday strongly condemned German authorities for allowing PKK followers to march in its city of Frankfurt.
It is unacceptable to see the symbols and slogans of the PKK, which are on the list of Germany's terrorist organizations, the spokesperson said in a written statement.
"It is impossible to explain for German authorities to claim that Turkey's elected representatives' meeting with their citizens is dangerous, but to treat terrorists as legitimate actors," Kalin added.
The spokesperson also condemned some European countries for trying to "interfere the referendum on April 16 in Turkey and take up a position in favor of 'No' vote."
With the increasing tensions between Germany and Turkey, German authorities has cancelled several Turkish high-ranking officials' visit and public rally in Germany since early this month, claiming reason of security problems or capacity limitation.
On the same day that PKK followers marched in Frankfurt, the deputy chair of Turkish ruling Justice and Development Party was banned from addressing local Turkish community in the northern German state of Lower Saxony.
