Migrant crisis: 'The legal crossing point from Serbia to Hungary'

The country has begun a new fast-track process for considering asylum applications, but there is still no certainty as to whether people will be allowed in.
The BBC's James Reynolds is on the Serbian side of the border with Hungary.
He says many migrants are waiting to get across and have been appealing to Hungarian police across the fence.
