European Union leaders are in Brussels today for an emergency summit aimed at tackling the spiralling migration crisis across Europe.
The meeting, which includes the Turkish Prime Minister, Ahmet Davutoglu, is yet another, convened to find solutions to the growing emergency.
Taosieach Enda Kenny will also be attending.
The latest figures reveal that more than 125,000 migrants and refugees have arrived in Europe so far this year.
Speaking ahead of the summit, British Prime Minister David Cameron described the migration and refugee crisis as "the greatest challenge facing Europe today".
German and Dutch leaders, Angela Merkel and Mark Rutte, met Turkey's Prime Minister late on Sunday night for pre-summit talks.
It is understood that all 28 European Union leaders will agree that member states must use "all available means" to stem the flow of people into the EU, but it is not yet clear quite what that means.
Closure of Balkan corridor?
The summit is likely to conclude formally that the so-called Balkan corridor, the route migrants have been taking from Greece, through the Balkans to Western Europe, is now closed.
That would represent an EU-level acknowledgment of a situation that has been a fact on the ground for two weeks.
More than 30,000 people are trapped on Greece's northern frontier following a unilateral decision by Macedonia to close its border.
Aid agencies are warning that the situation is fast becoming a humanitarian catastrophe with the number of people trapped expected to climb to 150,000 within weeks.
It is not clear how the EU leaders propose to ease or solve the problem. To reopen the Macedonian border would only restart the flow and anyway, Macedonia is not a member of the EU, and cannot be compelled to reopen its border.
The closure of the Macedonian border has also re-energised the business of people trafficking.
There will be discussion on a proposal with Turkey to take back all those migrants who arrive in the EU via Greece who are refused asylum.
A proportion of arrivals in Greece are economic migrants rather than refugees fleeing war. Economic migrants are routinely refused asylum.
