"I've seen more than ever before, and came back concerned"

The Balkans can easily become one of the chessboards where the big power game can be played, EU foreign policy chief Federica Mogherini said on Monday.

Mogherni made the remark following the meeting of EU's Foreign Affairs Council, when a reporter asked how deep the concern was about Russian interference in the Western Balkans - "and to what extent are member-states seeking action in that regard."
