Reuters: Ukraine’s biggest drone attack on Moscow kills one, disrupts air and train transport … the Night before the US-Selensky Peace Meeting in Saudi

Overnight, Ukraine operated the largest drone attack on Moscow. It failed, all drones shot down. Small damages from debris, but one killed. At the same time, Ukraine attacked some small Russian border towns, 3 deaths.
Why did Ukraine do this the night before the most important meetings between the US delegation and V Selensky in Jeddah? Does Ukraine want to provoke Russia? Does Selensky want to disturb the peace negotiations between the US and Russia?
The US decided to stop the proxy war in Ukraine, a lost case. Does the proxy go wild? Hoping to become the proxy of some European leaders? Such drone attacks will certainly not help Selensky to restore his relations with the Trump Administration.
