Migrants protest at closed Hungary-Serbia border
Migrants who have been stopped at the Serbian border have started to protest at not being allowed to cross to Hungary.
Some people were holding up signs reading "No food" and "No water", in what appeared to be a hunger strike.
Hungary declared a state of emergency in two southern counties as tough new laws to stop migrants entering illegally came into force.
Police said they had arrested 60 people accused of trying to breach a razor-wire fence on the border with Serbia.
