Russia attacked Ukraine at night. They used a new missile. It is called Oreshnik. This missile hurt many things. Sadly, four people died. Twenty-five people were hurt in Kyiv. Kyiv is the capital city. The attack was late Thursday. It also broke buildings in Lviv. Lviv is in western Ukraine. This makes people worry more. They worry about the war. They also worry about safety.
Russia said Ukraine attacked President Putin's home. This happened in December. Ukraine officials say this is not true. Andrii Sybiha is Ukraine's Foreign Minister. He said Russia's reason is wrong. He called it "hallucinations." He said the attack is a danger to Europe. Lviv is near Poland. This could cause problems.
The Oreshnik missile is very fast. It travels far. Russia has not used it much. It can break into many parts. These parts explode. Videos show the strong attack.
Russia wants to scare Ukraine. They also want to show strength. They are angry about peace talks. They are angry about soldiers in Ukraine. This could change the war.
This attack shows Russia is tougher. The European Union does not think Ukraine attacked Putin's home. It is hard to know what is true. The world must now deal with this.
