THESSALONIKI, Greece — Greece's foreign minister has voiced concerns about at a new Syrian real estate law that would force refugees to return home if they want to keep their property in Syria.

Foreign Minister Nikos Kotzias says the law does not secure the properties of millions of Syrians who are now displaced outside the country. He says it will make their eventual return to Syria much more difficult.

The decree, made public last month, gives property owners in some parts of Syria one month to provide ownership deeds or face confiscation of their property.

Thousands of Syrian refugees have sought asylum in Greece.

Kotzias spoke during a southern Balkans ministerial meeting Friday in the northern Greek city of Thessaloniki.
