A Ukrainian aerial attack on a Russian region some 1,900 kilometers from the border wounded at least 11 people, as Ukraine's military claimed it targeted a weapons factory there with new long-range cruise missile.

Officials in the central region of Udmurtia said some of those wounded were hospitalized in the attack, which they said involved Ukrainian drones targeting an unnamed facility.

Ukraine's military, however, said the facility was the Votkinsk factory, a sprawling complex where several major Russian weapons systems are manufactured including Yars, Iskander, and Oreshnik missiles.

Video posted to several Telegram channels also purported to show fire and smoke at the Votkinsk factory.

In a post to Telegram, the military also claimed the factory was hit using a new long-range cruise missile called the Flamingo. The missile, which first started appearing last year, is being developed by the Ukrainian company Fire Point.

The company's chief designer published a video on February 20 showing a launch of the missile with the caption: "Here's a short video. No context. Context later."

Military experts are cautious about the Flamingo's abilities, but Ukrainian officials, who have begged Western allies for cruise missiles like Tomahawks and Storm Shadows, are hoping to ramp up production of the homegrown weapon to increase their ability to hit targets deep in Russia.

Russia, meanwhile, pounded Ukraine's Black Sea city of Odesa overnight, hitting a power facility, while launching scores of drones and missile at targets across the country. At least two people were injured in the barrage.

A Russian drone hit a school building, while another drone slammed into a power generating substation, according to private energy company DTEK.

In the northeast city of Sumy, Russian strikes hit a residential district, injuring an elderly woman and two children, police officials said.
