Ukraine war: Two UK aid workers captured by Russia, says NGO

An aid organisation has said Paul Urey and Dylan Healy have been captured by the Russian military

Two British volunteers providing humanitarian assistance in Ukraine have been captured by the Russian military, an aid organisation has said.

The non-profit Presidium Network said Paul Urey and Dylan Healy were detained at a checkpoint in southern Ukraine on Monday.

The Foreign Office is said to be urgently seeking more information.

Mr Urey's mother said she was extremely worried for his welfare, because he has type 1 diabetes and needs insulin.

Meanwhile, Russia has released a video of a man who it says has surrendered to Russian troops.

The man, who is wearing a military camouflage uniform, said he was called Andrew Hill, from Plymouth, and has children and a partner.

In the video, the man who is shown with a cast on his arm, asked if he was safe and if he could be taken to a hospital.

The video has not been verified by the BBC and it is not clear whether the man is speaking under duress.

The city of Zaporizhzhia took in many people fleeing besieged Mariupol, but was also shelled itself

The two captured aid workers are believed to have been working independently, but were in touch with the Presidium Network.

They were said to be trying to rescue a family from a village south of the city of Zaporizhzhia at the time of their capture.

In a statement passed on by Presidium, Mr Urey's mother Linda said she was "extremely worried".

Speaking to the BBC at her home near Preston, she said she had not been able to eat or sleep.

"I miss him, I can't cope with it," Ms Urey said. "Please give him back, he's a family man, he's my carer."

Ms Urey said before leaving the UK, her son, who is in his 40s, said he could not sit there and "watch people dying".

"Please let him come home to me, to his kids, to his dog," she said.

Presidium said Mr Urey, who is is from Warrington, Cheshire, had previously spent eight years as a civilian contractor in Afghanistan. He had been living in Leyland, Lancashire, prior to travelling to Ukraine.

Mr Healy is described as a chef by training, originally from Huntingdon in Cambridgeshire. He was driving the car at the time of the men's capture, Presidium said.

Presidium Network's founder, Dominik Byrne, told the BBC it had taken the men six hours of negotiation to get through the last Ukrainian checkpoint and into Russian-controlled territory, where they were detained.

Mr Byrne said he was making an appeal on behalf of the captured men "to get the support we need from the UK government and from the international community, as well as on the ground".

He said he also wanted "to get clarification about how they are and how safe they are" and to know whether they were being "treated properly".

On Thursday, the government confirmed that one Briton had been killed in Ukraine and another was missing.

Sources in Ukraine told the BBC the dead man is Scott Sibley, who is understood to have been fighting for Ukrainian forces.

Two other British men, Aiden Aslin, 28, and Shaun Pinner, 48, were captured earlier this month while fighting in the south-eastern city of Mariupol and shown on Russian state TV with apparent facial bruising.
