Fighting has ramped up in Ukraine as the war approaches its third anniversary.
This week, Ukraine ramped up long-range drone strikes into Russia, targeting oil facilities that fuel warplanes, ships and military vehicles as well as oil refineries that help power the economy.
An increase in the intensity of the attacks appears to have started in December, continued through the whole of January and is still being maintained into February, according to analysis of drone strikes confirmed by the Ukrainian armed forces and security services.
So what else is happening on the ground at the moment?
Ukraine holds a small part of Russia’s western Kursk region.
Meanwhile, Russia occupies around 20% of Ukraine – including parts of Luhansk, Donetsk, Zaporizhzhia, Kherson and Crimea.
On the southern front, Ukraine has lost the city of Toretsk but is holding onto Chasiv Yar and Pokrovsk.
