Powerful explosions happened in Moscow. This has raised worries about Russias ability to protect its capital city. The wars effects are now getting closer to Russias center of politics.
Moscow has been seen as a safe city in Russia for a long time. It has mostly stayed out of the conflict.. The recent blasts have changed that. They have shown that Russias security has some spots.
The attacks also have a lot of meaning. Moscow is where Russias government and military leaders are based. If there is an attack near the capital it makes the Kremlins message of being in control seem less believable.
We do not know everything about what happened.. The explosions show that the war is now affecting even Moscow. Moscow is not safe, from the war anymore.
