Mayor Ihor Terekhov wrote on Telegram on Monday that Russia has once again launched heavy air attacks on Ukraine, with 19 people injured in the large city of Kharkiv in the east of the country.

According to what he wrote, the city was hit by a repurposed S-400 air defence missile.

In the south-eastern Ukrainian, a child was injured, and infrastructure facilities as well as residential buildings were damaged, according to the regional administration.

Governor Ivan Fedorov wrote of a massive drone attack.

According to Ukrainian military observers, Russian troops have also advanced further in the Donetsk region and have taken control of two villages.

Ukraine has been defending itself with Western assistance against a large-scale Russian invasion for more than two and a half years but is currently under significant pressure.
