Kyiv experienced a large air attack overnight. Ukraine's air defence systems worked hard. They stopped most of the incoming weapons. However, damage was reported in one area of the city.
At the same time, Ukraine announced a successful attack inside Russia. Ukrainian forces hit oil facilities in the Caspian Sea. This is a significant development in the conflict.
The United Kingdom and Sweden have also made important announcements. They will provide more help for Ukraine's defence. This support also strengthens security in the region.
On Monday morning, more weapons fell on Kyiv. Ukrainian air defence units fought back strongly. A fire started in one district. The exact damage is still being checked.
Ukraine's army said they hit three oil platforms. These platforms are in the Caspian Sea. They belong to the Russian company Lukoil. This attack could affect Russia's oil business. It might also affect how Russia pays for the war.
The UK plans to build a new missile for Ukraine. This missile will help Ukraine attack from far away. It is called "Nightfall." This will allow Ukraine to hit Russian bases far from the front lines.
Sweden is also giving money to improve its air defence. This shows Sweden is worried about security. Many European countries are increasing their military readiness. The situation is becoming more serious.
