TIRANA, Albania - Albanian authorities have returned to Greece six Syrians who had illegally crossed the border.

Police said Saturday they arrested a 47-year old Albanian who had assisted the Syrians to cross in a mountainous area near Gjirokastra, 250 kilometres (155 miles) south of Tirana, for 300 euros ($335) each.

The Albanian is charged with assistance to illegal border crossing, which is punishable by up to seven years' imprisonment.

Albania is co-operating with Italy and European agencies to get ready for a possible flow of migrants, though it hasn't been a transit route so far.

Tirana has said it will neither open the border nor build a wall, calling for a joint European effort if the refugees' route turns to the tiny Western Balkan country.
