Turkish President Recep Tayyip Erdogan has described the Dutch as “Nazi remnants and fascists”, as a row grows over a cancelled Rotterdam rally, BBC News reports.
Earlier, the Dutch government withdrew landing permission for a plane carrying Turkish FM Mevlut Cavusoglu.
He was originally scheduled to speak at Saturday’s rally in support of a Yes vote in a referendum which would give Mr Erdogan greatly increased powers.
The rally was banned for security reasons, Rotterdam’s mayor said.
Turkey has now summoned the Dutch charge d’affair
“Ban our foreign minister from flying however much you like, but from now on, let’s see how your flights will land in Turkey,” President Erdogan said at a rally in Istanbul.
Mr Cavusoglu also warned Turkey would impose heavy sanctions if his visit were blocked.
Dutch Prime Minister Mark Rutte said in a statement (in Dutch) that the Turkish threat of sanctions made “the search for a reasonable solution impossible”.
Therefore the Netherlands was withdrawing landing rights, he said.
The diplomatic row comes just days before Dutch voters go to the polls.
