COLOGNE, Germany (APP) - Tens of thousands of members of Germany 's Turkish community rallied in the city of Cologne Sunday, in a show of support for President Recep Tayyip Erdogan following Turkey's failed coup .
Police said some 20,000 people had joined in the demonstration staged by groups including the pro-Erdogan Union of European-Turkish Democrats (UETD).
Waving the red Turkish flags , the demonstrators kicked off their rally singing both Turkey's and Germany 's national anthems before observing a minute's silence for those killed in the July 15 putsch, as well as for victims of recent attacks including in Paris and Munich.
