Spanish rescue services say they have intercepted 301 migrants trying to reach Spain from Morocco in 12 boats over the past three days.

The service said 84 migrants were brought ashore Monday from three boats spotted off southwestern Spain.

The rest were intercepted Saturday and Sunday at points further east along the southern coast.

The service said that between Jan. 1 and Aug. 31 it helped rescue some 4,188 migrants, 2,307 of whom were taken to Morocco by marine services from that country.

African migrants seeking a better life in Europe often try to reach Spain by crossing the Mediterranean Sea from Morocco.

Tens of thousands of migrants also try to make it to Italy and Greece from north Africa and the Middle East each year.

Leaders from the European Union and Turkey will be fine-tuning a plan to help Ankara cope better with refugees from Syria and Iraq and limit the flow of people leaving to Europe.

President Recep Tayyip Erdogan was arriving in Brussels Monday for talks with EU Council President Donald Tusk, Commission President Jean-Claude Juncker and Parliament President Martin Schulz.

Commission spokesman Margaritis Schinas said Monday that the EU wants to "have a contract of mutual confidence that is necessary, given the central role Turkey has played in the refugee crisis."

Turkey hosts around 2 million refugees, many from Syria and Iraq.

Tens of thousands of people fleeing conflict and poverty have been crossing from Turkey into Greece in the hope of finding better lives in Europe.

A spokeswoman for the EU's border agency says it is seeking hundreds of additional border guards to help in the task of identifying migrants that are arriving in Europe.

Ewa Moncure said Monday that Frontex appealed to EU and Schengen members last week to jointly provide 775 experts in identification and interpreters. They would be deployed this month to Greece and Italy, which are taking the brunt of the migrant wave.

The agents would reinforce the procedure of identifying people who qualify for political asylum, like Syrians and Afghanis, and economic migrants, who will be returned home. The current numbers of border guards are insufficient to meet the migrant wave of some 420,000 people so far this year.
