The Dutch government has withdrawn landing permission for the Turkish foreign minister's aircraft, drawing the ire of the Turkish president and escalating a diplomatic dispute between the two NATO allies.
The Dutch government said in a statement on Saturday it had withdrawn the permission because of "risks to public order and security" caused by the proposed visit of Foreign Minister Mevlut Cavusoglu to Rotterdam.
Turkish President Recep Tayyip Erdogan promised retaliation against Dutch diplomatic flights.
"You can stop our foreign minister's plane all you want, let's see how your planes will come to Turkey from now on," Erdogan said at a rally in Istanbul.
"They do not know politics or international diplomacy," said Erdogan and added, "these Nazi remnants, they are fascists" with the crowds booing.
Earlier on Saturday, in an interview with private broadcaster CNN Turk, Cavusoglu said: "If the Netherlands cancels my flight permit, our sanctions to the Netherlands would be heavy."
He also repeated the government's charges that bans on rallies are "fascist practices".
Cavusoglu said the German and Dutch bans on campaigns for a "yes" vote in Turkey's April 16 referendum on constitutional changes means Europe is "taking a side for a 'no' vote."
The constitutional changes would give the president more powers.
The Dutch government said it had been searching with Turkish authorities for an "acceptable solution" to Cavusoglu's plan to campaign in the Netherlands but "before these talks were completed, Turkish authorities publicly threatened sanctions. That makes the search for a reasonable solution impossible."
The diplomatic row comes just days before the Netherlands goes to the polls in a March 15 election for the lower house of Parliament.
The campaign has been dominated by issues of identity, with anti-Islam lawmaker Geert Wilders set to make strong gains.
Ahead of Saturday's decision, Wilders had accused the government of a weak response to Turkish plans to send ministers to the Netherlands to campaign.
