Migrant crisis: On the road from Serbia to Slovenia

The Croatian prime minister has said migrants entering his country will be "moved on" after more than 17,000 people, many of them refugees from Syria, arrived since Wednesday.

The huge influx followed Hungary's decision to close its borders with Serbia.

On Friday, some of those migrants already in Croatia headed to Slovenia, from where they hoped to enter Austria, then Germany.

Europe correspondent Lucy Williamson joined them on their journey.
