Mobile-phone video shows wrecked residential buildings with no windows, and fallen trees and power lines, in the aftermath of strikes that killed at least 11 people in Kharkiv, Ukraine’s second largest city on Monday.

Kharkiv’s regional administration chief said artillery had pounded residential districts. The city has been the target of some of the worst aerial attacks since Ukraine was invaded by Russian forces

Pundits and officials turn to ‘mythbusting’ as evidence of Ukraine destruction undermines official line

• Russia-Ukraine war – latest updates

Russian state television talkshows are describing videos of missiles striking Ukrainian cities and reports of Russian soldiers killed in action as “fakes”, as the country’s media try to account for photos and video emerging from Ukraine that contradict official reports of the invasion.

The “mythbusting” is one of the adjustments that TV propaganda shows have had to make as evidence of the growing destruction in cities such as Kharkiv and Kyiv makes it increasingly difficult for the government to present the fiction of a concentrated offensive in the Donbas region.

Five people have been killed and several wounded in a Russian attack on a TV tower in Ukraine's capital, Kyiv, according to reports.

Two explosions were heard in the Borshchahivka and Dorohozhychi areas, said the news agency Interfax-Ukraine, knocking several channels off air.

The incident was first reported on social media by the Ukrainian interior ministry adviser, Anton Herashchenko, moments after Russia warned Kyiv residents to evacuate military and intelligence infrastructure

In the satellite image, the trees of the forest just north of the Ukrainian village of Rudnya-Shpylivska – population 107 – appear as if you could brush them with your hand.

Before last week, this hamlet was almost too small to notice, a place that cars would speed past on the P02 highway, those trees a blur.

The ‘vacuum bomb’, which Ukraine says the Russians have used in the invasion, ignites a fireball that sucks in all surrounding oxygen

• Ukraine invasion: latest updates

Fears have risen over the use of thermobaric weapons by Russia after the Ukrainian ambassador to the US said a vacuum bomb – another term for the weapon – had been used during the invasion.

The use of such weapons, which suck in oxygen from the surrounding air to generate a high-temperature explosion, has yet to be independently confirmed, though footage from Ukraine has shown thermobaric rocket launchers on Russia’s TOS-1 vehicles.
