An American citizen suspected of being an Islamic State activist is stuck on the border between Greece and Turkey, after Turkey has deported him.
The alleged militant was deported on Monday as Turkey launched a campaign to repatriate captured jihadist fighters held in its prisons.
Greek police said they refused him entry when he tried to cross the border near the Greek city of Kastanies.
The man would have spent the night stuck between the two borders.
The Turkish news agency Demiroren named him Muhammed Darwis B. He would be an American citizen of Jordanian origin.
A Turkish official told the AFP news agency that he had refused to be returned to the United States and had asked to be sent to Greece.
On Tuesday he was still stuck on a strip of road between the two countries and witnesses said he was trying to shout at Turkish reporters.
The fate of foreign ISF combatants has been a key issue since the group's defeat on controlled territory in Syria and Iraq.
Turkish President Recep Tayyip Erdogan said 2,500 of these activists are in prison in Turkey.
Case unfinished since the defeat of the EI
There can be only a few more illustrative illustrations than that of the unfinished business left behind by the military campaign of the US-led coalition to defeat the IS.
More than 70 countries have come together to defeat and dismantle the jihadist caliphate that terrorized huge gangs of Iraq and Syria. But like other military campaigns in the Middle East, they have not sufficiently planned the consequences.
As a result of the final battle against ISIS in Baghuz, Syria in March, thousands of IS fighters and their dependents were interned in camps. Turkey, which has been arresting EI members for years, now has about 2,000 in its prisons.
Turkey, Iraq and the Kurdish authorities all want Europe and the West to hurry to take back their citizens, but until now, governments have been extremely reluctant to do so , partly for fear of the failure of the lawsuits.
Turkey's current expulsions now threaten to force them to act.
Who else has expelled Turkey?
The Turkish Interior Ministry said that he had also expelled Monday a Dane who would be a member of the IS. The Danish authorities have stated that their citizen was arrested when he arrived in Copenhagen.
Germany said one of its citizens had also been deported.
Turkey said that more than 20 other European suspects, including 11 French citizens, two Irish nationals and several other Germans, were being repatriated to their home country.
Turkey has long accused Western countries of refusing to take responsibility for citizens who have joined the Islamic State.
Germany, Denmark and the United Kingdom have repeatedly deprived their citizens of citizenship for allegedly joining jihadist groups abroad, with the aim of blocking their return.
The United Kingdom reportedly withdrew the citizenship of more than 100 people, including Shamima Begum, an IS group recruit who left London when she was a teenager.
On Tuesday, the UN chief, Antonio Guterres, called for international cooperation to solve the problems related to foreign jihadists, claiming that it does not belong to Syria and Syria. Iraq "to solve the problem for everyone".
The UN has previously said that countries should take responsibility for their own citizens, unless they are prosecuted locally, in accordance with international standards.
Turkey has not confirmed whether the returnees were seized in Syria or on Turkish territory.
Some IS members and their relatives were captured in northeastern Syria in October, when Turkey launched a cross-border operation against Kurdish-led Syrian Democratic Forces (SDF).
At the time, the SDF had announced the detention of more than 12,000 alleged ISI members in seven prisons in the region, including at least 4,000 foreigners.
Relatives of suspected ISI militants were also detained in several IDP camps, the largest of which, al-Hol, was home to nearly 70,000 people.
How will the repatriations proceed?
A French Foreign Ministry source told the AFP news agency last week that suspected jihadists were often sent back to France from Turkey under an agreement signed in 2014.
"Jihadists and their families are routinely sent back to France and arrested as they leave the plane, most of which is done in secret.The news is neither published nor published much more late, "said the source.
The German Interior Ministry said this week "that he did not want to oppose the return of German citizens".
An official of the German Ministry of Foreign Affairs confirmed that a judicial procedure involving at least three men, five women and two children was under way in Turkey.
On Monday, a Dutch court ruled that the country should take over the children of Dutch women who joined IS, but not necessarily their mothers.
Some 23 Dutch women and their 56 children are currently being held in detention camps in Syria, AFP reported.
It is unclear whether Turkey will be able to repatriate people suspected of having been victims of the identity of their country of origin.
