Five countries in Europe think Russia hurt Alexei Navalny. He was a leader who spoke against the government. These countries have lab tests. The tests show he was given a strong poison. This poison was in a sample from Mr. Navalny.
The countries told a group called the OPCW. This group works on chemical weapons. The countries say Russia broke a rule. This happened at a meeting.
The United Kingdom, France, Germany, Sweden, and the Netherlands made a statement. They believe Mr. Navalny was poisoned. The science tests prove it. Epibatidine is a very bad poison. It is made in labs.
Alexei Navalny died on February 16th. He was in a prison. He spoke out against bad things. Many people were angry when he died. His friends thought it was for politics. Now these countries agree.
The UK said Russia had the chance to use the poison. It was not an accident. It was to stop him from talking.
Telling the OPCW is a big step. It might start more checks. This poison is very dangerous. It can be deadly.
This will make Russia and Europe more upset. The OPCW will check the claims. Mr. Navalny's death is sad. It shows danger for people who disagree with Russia.
