Turkey and the Netherlands are embroiled in a diplomatic row after the Dutch government barred Turkish ministers from entering the country to campaign for referendum due to take place next month. A private jet carrying Turkish foreign minister Mevlut Cavusoglu was denied permission to land in Rotterdam on Saturday while the country’s family minister, Fatma Betül Sayan Kaya, was blocked from entering the Turkish embassy in the city and escorted back to the German border later that night.
