The discovery of almost a hundred migrants found stripped naked near the border between Greece and Turkey marks a new low in Europe’s problematic treatment of people seeking asylum.

And the incident has sparked a bitter dispute, largely on twitter, between the two countries as well as calls for an urgent investigation.

The two countries have blamed each other for the apparent mistreatment of the 92 men, after images shared on social media shocked people across the globe.

The UN’s refugee agency UNHCR has said it is “deeply distressed” by the reports.

“UNHCR is deeply distressed by the shocking reports and images of 92 people, who were reported to have been found at the Greek-Turkish land border, stripped of their clothes,” UNHCR said in a statement.

“We condemn such cruel and degrading treatment and call for a full investigation into this incident,” it said.

Meanwhile, Turkey and Greece have blamed each other for the incident. Greece’s Minister of Migration and Asylum, Notis Mitarachi, tweeted a photograph of what he implied were some of the migrants at the border, accusing Turkey of shameful behaviour.

“Turkey’s behaviour toward 92 migrants whom we rescued at the borders today, is a shame for civilization. We expect Ankara to investigate the incident and protect at last, its borders with the EU,” he tweeted.

Local reports have not made it clear why the men in the photo were not clothed.

Greek police said in a statement that its forces had “discovered 92 illegal migrants without clothes and some of them with injuries on their bodies,” near the country’s northern border.

Greek authorities claim the migrants were pushed into Greece across Evros River in small boats from Turkish territory.

The authorities said they had immediately provided the migrants with clothing, food and first aid.

“Turkey continues to openly instrumentalise immigrants, violate human rights, [and] violate International law,” the statement continued.

Turkey has denied involvement in the incident.

“As you couldn’t find one single case of human rights violation by (Turkey), you just seek to expose [the] image of your cruelty you’ve inflicted as if (Turkey’s) done it,” Turkey’s  Deputy Interior Minister Ismail Catakli tweeted in response.

Catakli also accused Greece of “manipulations and dishonesty,” in his tweet.

Greece last year finished building a 40-kilometre wall along its border with Turkey amid concerns that the Taliban’s takeover of Afghanistan could cause an influx of people seeking asylum.

The country was at the centre of Europe’s migrant crisis in the mid-2010s, when millions of refugees and migrants from Syria, Afghanistan and Iraq travelled to Europe.

It has taken a hard line approach since then, rebuffing pleas from Turkey and international organisations to allow more migrants through its borders.

Meanwhile, at least 18 migrants died last week in a deadly sea crossing from Turkey to Greece.

It was one of the deadliest in recent years and experts fear more may follow as tension between Greece and Tukey soars in the Aegean Sea that divides them.

When huge waves capsized the boat, with dozens of Somali woman aboard, it was cast onto the rocky shores of the rugged Ismahan Island.
