Russia today launched its biggest drone and missile attack in months in Ukraine, killing 10 people and wounding at least 60 in Kiev, the south, west and east of the country, according to Ukrainian officials.

Russian forces fired about 110 missiles today in one of the largest airstrikes in Ukraine, Ukrainian President Volodymyr Zelensky said, noting that most of them were shot down.

Dozens of people were injured and damage was reported to a maternity hospital in the city of Dnipro in central Ukraine and in buildings in Lviv, in the western part of the country, in Odessa, in the southeast and in Kharkiv in the east.

Two people have been confirmed dead in Kyiv, while more are believed to be trapped in the rubble of a warehouse damaged by falling munitions debris, the mayor of the Ukrainian capital Vitali Klitschko said in a Telegram post.

Two people were killed in Odessa and at least 15 were injuredn, including two children, from rocket strikes on residential buildings, according to the governor of the Odesa region.

In the Lviv region, which borders Poland, it was confirmed that critical infrastructure facilities were affected, the presidential office said, declining to specify what type of infrastructure was affected.

The country’s Ministry of Energy announced at the same time that residents of four regions in the north and south of the country are facing power outages after today’s massive Russian air attack with missiles and drones.

“The enemy targeted social and vital infrastructure,” said Prime Minister Dennis Schmihal.

The chief of the general staff of the Ukrainian army also said that today’s Russian airstrike targeted military installations, while the Ukrainian army announced that its air defense system shot down 27 drones and 87 cruise missiles launched by Russian forces.

“We can say that it was a mass attack,” Yuri Ikhnat, the spokesman for the Ukrainian air force, told television networks.

Hypersonic, cruise missiles and ballistic missiles, including the X-22 type, which are extremely difficult to intercept, were used, he added in comments to television networks.

Ukraine has been warning for weeks that Russia may be stockpiling missiles to launch a major air campaign against the Ukrainian energy system. Last year millions of people were plunged into darkness by Russian power grid strikes.
