Turkey vows 'harshest' retaliation to Dutch ban

Netherlands prevents leading Ankara govt officials from attending rallies

ANKARA/THE HAGUE - Turkey told the Netherlands on Sunday that it would retaliate in the "harshest ways" after Turkish ministers were barred from speaking in Rotterdam in a row over Ankara's political campaigning among Turkish emigres.

President Recep Tayyip Erdogan had branded its fellow NATO member a "Nazi remnant" and the dispute escalated into a diplomatic incident on Saturday evening, when Turkey's family minister was prevented by police from entering the Turkish consulate in Rotterdam.
