America has new rules. These rules are for a group. This group sent old soldiers. They sent them from Colombia. They sent them to Sudan.
The soldiers fought with the RSF. The RSF did bad things. The group has people and companies. They sent fighters. This made Sudan's problems big.
Last year, people saw fighters. America's leaders said about the rules. A man named Álvaro is key. He is from Colombia.
These fighters are good at fighting. They fought in Colombia. They know about weapons. They may have taught child soldiers.
Money for this group was hard. Mateo managed companies. These companies paid the soldiers. His companies sent money. Mónica also helped with money.
Colombia says sorry. America's rules stop the RSF. America calls this a war crime. The rules stop their money. This will help Sudan.
