Kharkiv : At least six people were injured in an explosion, including a child, in Kharkiv, Ukraine's second biggest city. The incident was reported by Ukraine’s State Emergency Service on Tuesday in a Telegram post.

According to videos of the incident posted by the Ukrainian Ministry of Foreign Affairs (MOFA) and Ukrainian government officials, the blast destroyed a government building. The clips were posted on social media early Tuesday local time.

“Russia is waging war in violation of international humanitarian law. Kills civilians, destroys civilian infrastructure. Russia’s main target is large cities that are now fired at by its missiles,” the Ukrainian MOFA tweeted Tuesday, sharing a video showing what appears to be a missile attack on the Kharkiv Regional State Administration building.

Another video by Kostiantyn Nemichev, the Head of Defense Staff of Kharkiv, showed the effect of the strike, including inside of the building which had been reduced to rubble.

The Regional State Administration building houses local government offices. It is located in "Freedom Square" — the main square of Kharkiv and an architectural landmark.

Anton Gerashchenko, adviser to Ukraine's Minister of Internal Affairs, also shared a video on his official Telegram account taken from street level at Freedom Square. The video shows the site of the explosion, and the debris on the ground where the Kharkiv Regional State Administration building once was on.
