Swathes of people descended on the camp as the Greek authorities tried to evacuate an estimated 11,500 people already stranded in its squalid conditions. 

Pressure on the decrepit make-shift settlement has grown after Balkan states slammed shut their borders, cutting off the migrant route to the European Union.

About 250 people of all ages conveyed a message of peace as they gathered by the railway tracks and the border fence, singing and shouting slogans while they were watched by Greek police in riot gear.

Many elderly handicapped refugees were sitting in wheelchairs sobbing while many other people, who had dismantled their tents in order to be ready to cross the border quickly, were waving white handkerchiefs.

'No violence, we just want to cross,' read one banner, while another said: 'Freedom of movement is everybody's right.'

Some in the crowd, however, attempted to move towards the police line but were blocked by others who formed a human chain.

However, arguments did erupt within the crowd when Syrians and Iraqis accused the Afghans and Pakistanis of wanting to push their way through, one witness said.

The wave of new arrivals appeared to be triggered by a rumour that journalists and Red Cross officials would help them force their way across the fence into Macedonia, a young Syrian refugee said.

He said: 'We heard today that the border will open and we came here to cross. They told us the Red Cross and 500 journalists from all over the world will be with us.

Another young Syrian said his sister, who is living in Germany, had seen the same claim on the Internet and alerted him.

Qasim Mosawy, from Afghanistan, said: 'People have been here for a long time. I think it's very dangerous to cross, especially for the children but what should we do?'

Dozens of other migrants could be seen heading through the fields, carrying babies, towards the Idomeni crossing. 

'We are trying to step up our information campaign to the refugees. Some people, for reasons we don't understand, are creating false hope,' said Giorgos Kyritsis, spokesman for the SOMP agency which is coordinating Athens' response to the refugee crisis.

Using loudspeakers, Greek officials told those gathering that the crossing would remain closed, repeating the message in both Arabic and Farsi, ANA said.

Two weeks ago, hundreds of people were stopped by Macedonian troops after crossing a surging river on the border. 

Bypassing the regular crossing, they tried to wade through the fast-flowing water, clinging to a rope strung between the banks.

Three Afghans, including a pregnant woman, drowned. The rest were stopped by Macedonian troops and sent back to Greece.

'Macedonia will not allow (the) reopening of the Balkan route,' Ivica Bocevski, a representative of Macedonian President Gjorge Ivanov, said in the wake of the incident.

The bottleneck has left around 50,000 refugees and migrants stranded across Greece, which has stepped efforts to evacuate Idomeni.
