The latest developments in the hundreds of thousands of refugees and other migrants passing through Europe on their way west. All times local. 3:30 p.m. The Czech Republic is sending a unit of 25 soldiers to Hungary to help protect the external border of Europe's passport-free Schengen zone. Defense Minister Martin Stropnicky says the unit will be deployed for two months starting October 15. Stropnicky said Monday he was going to consult his Hungarian counterpart in Brussels on Thursday about further possible support for Hungary. Interior ministers of the Czech Republic, Slovakia and Poland will discuss further possible ways of helping Hungary, where about 300,000 migrants have arrived this year. --- 3:25 p.m. Poland has sent a helicopter and crew to Hungary to help patrol the border with Croatia. The mission is part of effort by Frontex, the EU's border agency, to beef up borders in face of the pressure from immigrants. Joanna Rokicka, spokeswoman for Poland's Border Guards, said Monday that a Border Guard chopper with eight crew members and one liaison officer was sent to Hungary on Sunday. The mission continues through Friday. Separate talks on more aid to help protect Hungarian border are being held ahead of Oct. 8 meeting of interior ministers from the Czech Republic, Hungary, Slovakia and Poland. Thousands of people seeking asylum in Europe are streaming into Hungary from Croatia as they search for paths toward Germany and other destinations in Western Europe. --- 1:40 p.m. 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. --- 1:15 p.m. 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. --- 1:00 p.m. 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. --- 11:25 a.m. The head of the U.N. refugee agency says a "positive relationship between the Western and the Muslim worlds" is essential to overcome refugee crises like those facing Europe. Antonio Guterres, the U.N. High Commissioner for Refugees, says there is an urgent need to fight fear of Islam and reduce the lure of extremist ideologies. He told his agency's executive committee on Monday that financing has fallen short to handle "mega-crises" like those in Iraq and Syria and other crises in South Sudan, Burundi, Yemen and Libya. He said "the humanitarian system is financially broke" and 33 U.N. appeals for assistance for 82 million people are 42-percent funded.
