As the raft appeared on the US side, the faces of the migrants became visible. More than half of them were children. Over March and April, more than 36,000 children crossed into the US unaccompanied by an adult. This was a record high for recent years.
Many children traveling alone set out on their journey hoping to reunite with a parent already in the US. More than 80% of them already have a family member in the country, the US government says.

But tonight he was frightened about what might await him in migrant detention centers in the US. He said he had heard stories about them.
"They will put us in an icebox and ask us questions," he said.
