Turkish officials and reports say 49 migrants have arrived in Turkey as part of a migration deal between Ankara and the European Union.

Ferries carrying migrants from the Greek islands of Kos, Chios and Lesbos reached the Turkish port towns of Gulluk, Cesme and Dikili on Tuesday, according to Turkish news agencies and an official at Dikili, who spoke on condition of anonymity in line with government rules.

According to the deal finalized last month, Turkey is to take back migrants who reached Greece after March 20. For every Syrian returned, Europe has pledged to take a Syrian refugee directly from Turkey to be resettled in an EU country.

Tuesday's group of migrants, from Afghanistan, Iran, Pakistan and Myanmar, was the third wave of migrants to be returned to Turkey.
