"Turkey should re-evaluate the issue of land crossings" under the March 18, 2016 migrant deal with the EU, Turkey's EU Affairs Minister Omer Celik was quoted as saying by the state-run news agency Anadolu.
The deal has sought to stem the flow of migrants from Turkey to the EU, in particular Greece, by land and sea routes.
Celik said migrant crossings across the Aegean Sea -- which have cost hundreds of lives -- should be prevented as a matter of human responsibility but the land portion of the deal should be reconsidered.
Turkey also pledged to take any necessary measures to prevent new sea or land routes for illegal migration from opening.

Turkey and the Netherlands have been locked in a crisis after the Dutch government banned Turkish ministers from holding rallies on its territory ahead of an April referendum on boosting President Recep Tayyip Erdogan's powers.
The Turkish leader likened the ban to "Nazism" and "fascism" and sharply warned the Netherlands would pay a price.
Erdogan also slammed Europe's silence yesterday, saying: "They don't bite each other."
But Celik said Mogherini had made a "completely wrong statement" with language that was inappropriate for her status as EU foreign policy chief.
