Talks at the informal EU summit in Salzburg, Austria, that ended on Thursday mostly focused on the refugee crisis and the Brexit, said Prime Minister Alexis Tsipras.

"The refugee crisis is the central political and ideological issues for the future of Europe and splits Europe into two camps," said the prime minister.

Greece is leading the camp that has a vision for Europe and is handling the big problems ahead, said Tsipras.

"Whoever wants Greece to move into the other camp, must think about it very well," he said, adding that "realism and logic must reign."

In the coming period, and this is the responsibility of Austria as presiding country, the procedures must speed up and priority must be given to the prospect of a fair review of the Dublin agreement, said Tsipras.

Additionally, Tsipras called for the speeding up of the creation of a European mechanism for civil protection, particularly after the fires in Greece and Sweden, and last year in Portugal.
