These pictures show how desperate many migrants' journey to Europe has become, as hundreds today tried to cross a fast-flowing river to flee from Greece to Macedonia.
Hundreds of them left the Idomeni camp, where thousands are stranded as they cannot overcome the border fence that is preventing them moving further north into Europe.
They crossed the river in an attempt to reach a weak point at the border.
The pictures even show small children, a baby and a man in a wheelchair being carried across the river, which was fast flowing after heavy rain.
Migrants also formed a 'human chain' to allow people, some carrying their belongings, to cross the river.
"We hope we can cross because we are a lot of people. Our number is big now," a 24-year-old Syrian called Aziz said, according to the BBC.
"We don't want to stay here in that camp, because we are tired of being there."
Those who crossed breached a gap in the border fence and made it out of Greece.
It is unclear how successfully many crossed the river successfully but Macedonian police and the army are detaining hundreds of migrants who have crossed over from Greece, the Associated Press reports.
UNHCR, The UN's refugee agency, said 19 migrants were placed in shelter in Macedonia after crossing the river and a further three were hospitalised.
A spokeswoman told The AP the border closure had forced migrants to take "desperate actions" to continue their journey.
Earlier on Monday, Macedonian Police found the bodies of two men and one woman, believed to be migrants, in the Suva Reka river, near the border town of Gevgelijar.
The border with Macedonia's closure has made it a scene of confrontation between police and migrants and hundreds of thousands of people try to enter Europe in the continent's biggest refugee crisis since the Second World War.
