After Russia launched another wave of drones and missiles, air raid sirens sounded in Ukraine.

The “biggest” drone attack to date, the mayor of Kyiv said, has injured five people.

The attack in southern Odesa killed one person. The Ukrainian Red Cross claims that its warehouse was attacked.

The attack on Kyiv is the fourth in eight days and just 24 hours after Russia celebrates Victory Day.

The holiday celebrates the Soviet Union’s victory over Nazi Germany in World War Two. This is a conflict that the Kremlin has been trying to compare with the full-scale invasion it launched of Ukraine last summer.

Moscow intensified air raids in the last week, ahead of an expected Ukrainian counteroffensive.

Ukrainian military officials said that the latest Russian raids, which lasted more than four-hours and began shortly after midnight, saw Iranian-made Shahed Kamikaze drones spread across the country.

Vitaliy Klitschko, the mayor of Kyiv, said that Russia had launched nearly 60 drones. He called it “the biggest” attack to date.

He said that he had destroyed all 36 drones over Kyiv. However, five people were injured by debris falling from the drones.

The BBC was unable to verify the numbers.

Kyiv’s military administration reported that emergency services were called after drone debris fell onto a runway of Zhuliany International Airport, one of the two commercial airports in the city.

The administration said that civilians were also injured when drone debris struck a residential building located in central Shevchenkivskyi.

Officials in Ukraine said that eight Russian missiles had been fired by bombers at targets in Odesa.

The Ukrainian Red Cross issued a statement saying that its warehouse containing humanitarian aid had been destroyed, and all aid deliveries were suspended.

Natalia Humeniuk was a spokesperson of Ukraine’s Southern Command. She later confirmed that a body – a guard – had been pulled from the wreckage.

The Ukrainian military command reported in a daily report that there were also a number of missile attacks on the Kherson region, Kharkiv, and Mykolaiv.

Local officials reported that at least eight people, including a child, were injured in two Kherson villages.

Vladimir Rogov, the Russian-installed administration’s head in Zaporizhzhia said that Russian forces had attacked a warehouse as well as a Ukrainian military position in Orikhiv.

The Ukrainian commander in Bakhmut, a besieged city in eastern Ukraine, said that Russian troops have intensified their shelling in an attempt to capture the city before Tuesday’s celebrations.

Since months, Russian troops, along with fighters from Wagner Group, a privately owned military company, are trying to capture Bakhmut – despite the strategic importance of this city.

The founder of Wagner, Yevgeny Prgozhin, appeared to have reversed his threat to leave the city over the weekend after being promised new ammunition by the Moscow defence ministry.

In the meantime, Ukrainian president Volodymyr Zelensky declared that 9th May will be celebrated from now on as Europe Day in accordance with the European Union. The move, which requires parliamentary approval, is seen as an affront to Russia.

Mr Zelensky claimed that he signed a law declaring that this day was to be a celebration of European unity, and the defeat “Ruscism”, which is a shorthand term for “Russian fascism”.

He said the 8th of May will now be officially a Day of Remembrance and Victory as it is celebrated in many countries across the globe.

The European Commission’s Ursula von der Leyen, the president of the European Commission, will meet with Mr Zelensky on Tuesday in Kyiv.

As Russia prepares for the Victory Day Parade on Moscow’s Red Square scheduled for Tuesday, the Kremlin has yet to announce what role President Vladimir Putin will play at the annual event.

In the VIP box, Mr Putin was seated with World War Two veterans and addressed the marching soldiers last year.

Russia has said that the leaders of Armenia and Azerbaijan as well as Belarus, Kyrgyzstan and Tajikistan are expected to attend the parade. This is despite the fact that major countries such the UK, US and France, who were all allies during the war with the Soviet Union, have snubbed the event.

A court in Berlin has banned the use of Russian and Soviet Flags during the 9 May rallies held at the Soviet War Memorials in Berlin.
