UNITED STATES : United States President Donald Trump has urged European nations to repatriate and prosecute jihadists from their countries who were captured in Syria. Otherwise, he warned, the US could release the terrorists to “permeate Europe.”

The IS fighters are being held by the Kurdish-led forces.

Mr Trump added that the IS caliphate was “ready to fall.”

“The US does not want to watch as these ISIS fighters permeate Europe, which is where they are expected to go. We do so much, and spend so much – Time for others to step up and do the job that they are so capable of doing,” he said in a tweet.

Otherwise, he said, the US would be forced to release them.

Syrian Democratic Forces (SDF) has said most of the fighters left in the town of Baghuz are foreigners, among the thousands drawn by IS leader Abu Bakr al-Baghdadi’s promise of a new jihadist utopia straddling the Iraqi-Syrian border and expunging national borders.

Trump administration officials have also said that they fear some of the detained fighters would put European countries at risk unless they are brought to justice.

President Donald Trump remarks echo those made by the UK’s foreign intelligence chief on Friday, who warned that the Islamic State group is reorganising for more attacks despite its military defeat in Syria.

Alex Younger also told of his concern about jihadists returning to Europe with “dangerous” skills and connections.

The president’s tweets come amid a controversy in the UK over the case of Shamima Begum, one of three schoolgirls who left London in 2015 to join IS.

She has said she wants to return, and her family in the UK have asked authorities to allow her to do so, but the government is making no attempt to bring her back to the UK.

On Sunday, Ms Begum’s family said they had been told she had given birth.
