Patrolling dirt paths on sun-baked hills bordering Greece, a European police team is helping Albania intercept more of the migrants trying to reach European Union states to the north.

The EU border and coast guard police Frontex deployed 50 officers with night vision cameras and vehicles two months ago at two border entry points favored by migrants, in its first operation outside the bloc's frontiers.

"We have seen a steady flow of migrants coming across from the Greek border. ... We are seeing apprehensions pretty much every day," said Krzysztof Borowski, a Frontex spokesman.
