Five countries in Europe have a new idea. They think Russia hurt a man. His name is Alexei Navalny. He was a man who spoke his mind.
These countries have tests. The tests show poison. This poison was in Mr. Navalny. It is a very bad poison.
The countries told a group. This group looks at chemical things. The countries say Russia broke a rule.
The United Kingdom and France agree. Germany and Sweden too. The Netherlands also agrees. They think Mr. Navalny was poisoned. The tests show this is true.
Alexei Navalny died in prison. He spoke out against bad things. Many people were sad. Now these countries say it was poison.
This is a big step. It means more checks. The poison is very dangerous. It can kill people. This is sad for Mr. Navalny.
