What life is like for kids trapped in Syria

Around a quarter of a million children are still thought to be trapped in Syria in the Middle East.
Many of them are in areas under siege, which means that they are surrounded by soldiers and can't get out.
Sieges are against important rules called international law, because soldiers attack ordinary people who aren't fighting and can't escape.
There has been a civil war going on in Syria for five years.
It's difficult to contact children who are living under siege, but refugees who left Syria recently have told us what life was like for them when they were still there.
