[Migrants argue with police near the Greek-Macedonian border, near the village of Idomeni]By Alastair Macdonald and Francesco Guarascio BRUSSELS (Reuters) - The European Union hopes a summit with Turkey on Monday can start putting an end to the chaotic arrivals of migrants in Greece and halt their treks through the Balkans toward Germany, diplomats said on Sunday. The meeting in Brussels will set out a tougher position on taking in migrants who reach Greece and formalise the closing of borders against those heading north from there. The EU leaders are also likely to tell Turkish Prime Minister Ahmet Davutoglu of their concern about human rights after the Turkish government seized control of a critical newspaper over the weekend.
