The European Union said on Tuesday it was "very concerned" about the crackdown at the Greek-Macedonian border where Macedonian police tear fired tear gas at hundreds of refugees.

"The commission is very concerned by the images we saw yesterday," European Commission spokesman Margaritis Schinas told a press conference.

Macedonian police on Monday fired tear gas as some 300 refugees forced their way through a Greek police cordon and raced towards a railway track between the two countries.

"It is up to the former Yugoslav republic of Macedonia to protect those borders. The images show once again that the only solution is a collective solution, a European solution," Schinas said.

"All measures on the borders must be in compliance with international law, and European law."
