The Ukrainian capital Kyiv has been subjected to a heavy air attack by Russia, the eighth time this month, leaving three people injured, reports BBC.
In video on social media, air defence systems can be seen shooting down missiles over the city.
Government messages warned people to keep away from windows as debris from intercepted missiles fell from the sky.
City mayor Vitali Klitschko said some rocket debris had fallen in central districts, including on the city's zoo.
The air raid alert sounded at around 02:30 (23:30 GMT Monday) and was lifted only two hours later.
The complex attack, which used both drones and missiles, was described as being "exceptional in its density" by one Kyiv official.
Serhiy Popko, head of the Ukrainian capital's military administration, described the barrage as being the "maximum number of attack missiles in the shortest period of time".
"According to preliminary information, the vast majority of enemy targets in the airspace of Kyiv were detected and destroyed," he added.
In the past few days, President Volodymyr Zelensky has been on a European tour, in which he has been promised several billion dollars' worth of military equipment by Western allies, including UK Prime Minister Rishi Sunak and President Emmanuel Macron of France.
Since Russia invaded Ukraine on 24 February of last year, thousands of civilians and combatants have been killed or injured, cities and towns have been destroyed in fighting, and nearly 8.2 million Ukrainians have been registered as refugees in Europe, with 2.8 million of them in Russia.
