One person has been killed in the Moscow region after Ukraine launched what appears to be its largest drone attack against Russia in three years.
Three people were also injured in the strike on the day that peace talks were set to begin in Saudi Arabia between Kyiv and Washington.
Most of the 337 drones were shot down over the contested Kursk region across the border from Ukraine.
But 10 regions were targeted in total.

The attack also damaged seven apartment buildings in the area and left a number of cars burning, according to Russian state news agencies RIA Novosti and Tass.
Flights were restricted in and out of six airports, and trains were temporarily suspended, according to local officials.
Moscow mayor Sergei Sobyanin claimed over 70 drones targeted the Russian capital and were shot down as they were flying toward it.
He also said that the country’s air defences had repelled the attack on Tuesday.
