Greek Prime Minister Alexis Tsipras says a summit of European Union and Balkan leaders on the migrant crisis is of little use if Turkey is not involved.

Greece has been facing the brunt of the crisis, as Syrians, Afghans and others by the hundreds of thousands flee their homelands through Turkey, across the sea to Greece and into the 28-nation EU.

Tsipras chided some EU nations for only looking at ways to keep migrants out and not how to tackle the crisis together.

"Unfortunately, till today, it was difficult to find a solution, because a series of countries adopt a stance of 'not in my own backyard,'" Tsipras said upon arriving at Sunday's summit in Brussels.

And he said Turkey bears a special responsibility in the migrant crisis.

Tsipras says "at the end of the (migrant) corridor, there is an entrance. So if we will not be able to agree with the country at the entrance, I am afraid that it will be very difficult to find a solution."

Greece's coast guard says a woman and two children aged 7 and 2 have drowned after their boat smashed into coastal rocks on the island of Lesbos amid turbulent seas.

The coast guard says the boat carried 63 migrants at the time and 53 of the passengers were rescued.

Based on information from other passengers, another seven are missing, it said.

The bodies of the dead have been recovered and two helicopters and two ships, from the Greek coast guard and from the EU border agency Frontex, continue the search.

The coast guard says the nationalities of the victims and those rescued have not been verified yet.

Dresden police said Sunday that about 100 people were involved in the fight overnight in the asylum center in nearby Niederau, the dpa news agency reported.

About 30 police officers helped break up the fight between an estimated 40 Afghans and about 60 others.

Serbia's prime minister is calling for a "comprehensive solution" to the migrant crisis at the upcoming summit of several EU and Balkan nations.

Aleksandar Vucic spoke Sunday before traveling to Brussels to meet the leaders of countries coping with the influx of tens of thousands of migrants hoping to reach Western Europe.

Vucic said he expects "hard, not very pleasant" talks, but hopes for a "comprehensive solution." He insisted Serbia is not afraid of its "responsibility" and will not "put up any walls."

But, Vucic also suggested his country will not agree to be the only migrant stop if countries further west close their borders.

Nearly 250,000 migrants have passed through the Balkans since mid-September and the surge is not expected to stop despite colder weather.

Croatia says a record number of 11,500 migrants have entered the country in one day in a sign that the flow of people toward Western Europe is not abating.

Interior Ministry spokesman Domagoj Dzigulovic said Sunday that the number of people who crossed into the country on Saturday was the highest in a single day since migrants started coming to Croatia in mid-September.

Migrants turned to Croatia after Hungary erected a barbed-wire fence along its border with Serbia. They now mainly travel from Turkey to Greece and then go north to Macedonia and Serbia before entering Croatia and move on to Slovenia and Austria. Most are aiming to get to Germany or Scandinavia.

Police say nearly 250,000 have crossed through Croatia since mid-September.
