Greek border police say they have rescued about 70 migrants stranded on a berm on the Greek-Turkish border after they crossed the river dividing the two countries and found the fields on the Greek side flooded following days of heavy rainfall.

The migrants, including women and children, were located early Friday after one of them called Greek emergency services. Their nationalities weren't immediately known.

Border police used inflatable dinghies to reach the group, who authorities say had been abandoned by the smuggler facilitating their journey. They were transported to a point further down the river and taken to a nearby village.

Greece is on the main route used by migrants and refugees attempting to enter the European Union. Tens of thousands enter the country annually.
