As the fighting in eastern Ukraine intensifies, humanitarian conditions in the region are deteriorating.
Sky News filmed families in the rebel-controlled capital of Donetsk, as it was revealed the European Union has extended its first set of sanctions against the separatists and Russia, which has been accused of aiding the rebellion.
Some of the families in Donetsk have been living in underground shelters since July, too frightened to let their children play outside or go to school.
Two hundred people, including more than 50 children, are living in the basement of an arts centre in the city's western suburb - afraid to allow the children above ground for more than a few minutes at a time.
One eight-year-old girl said she could not remember when she last played outside.
"If they go out it's only for five minutes maximum," her mother, Vika Makeeva, told us.
"To get fresh air and come back."
They said the school had been shelled and it had no basement shelter so the children had not been since December.
UNICEF has provided them with hygiene kits, and individuals have donated food and toys for the children.
"They started to shell us from the Ukrainian side," Luba, one of the mothers, said.
"I took the child when he was asleep in his blanket, put him on a bike and we went to a shelter in the children's hospital, but it was really damp, with frogs, and then we came here."
Many of the residents have homes, but they are too frightened to return.
We went with one lady to check on her flat - she told us their block was shelled four days ago, and their roof destroyed.
