Refugees Break Through Border Controls in Croatia

CLEAN: Croatia is at the centre of the migration crisis tonight, with thousands of people heading to its border from Serbia. Refugees desperate to reach western Europe, are finding alternative routes after Hungary erected a huge fence along its frontier. Croatian authorities began the day welcoming those crossing into their country but have quickly become overwhelmed by the numbers -- nearly seven and half thousand have crossed in the last 24 hours and the government is now saying it cannot take in any more. EU leaders will hold an emergency summit next Wednesday to try to find a common approach to the biggest refugee crisis in decades. Shows refugees crossing border.
