YEREVAN, MARCH 11, ARMENPRESS. Four planned Turkish political meetings in Austria were canceled on Friday in the latest signs of unease across Europe over a series of campaign events to rally support among expatriate Turks for President Tayyip Erdogan, Reuters reports.

A spokesman for police in the city of Linz said the private owner of a venue there had canceled an event featuring a party colleague of Erdogan.

The town of Hoerbranz near the German border canceled a separate event with a former Turkish minister because the organizers falsely labeled it as a book presentation.

Another event was scrapped in Herzogenburg, and a spokeswoman for a hotel in Wiener Neustadt, near Vienna, said it had canceled a meeting planned for Sunday.

Some European cities have blocked planned appearances by Turkish politicians to drum up support for Erdogan before an April 16 referendum on giving him sweeping new powers.

In separate developments, the mayor of Rotterdam said Turkey's foreign minister would not be allowed to campaign there on Saturday, and Swiss police canceled a speech by a Turkish politician planned for Friday, citing "significant security risks".
