British military intelligence souces say Russian forces are now deliberately targeting areas populated by civilians — a response to the Ukrainian resistance, which is slowing Russia’s advance. In spite of these increasingly brutal tactics, volunteers, including many from outside Ukraine, are signing up to join Ukraine’s army. Men between the ages of 18 and 60 have to stay in the country so they are available for conscription.Despite all those volunteers, the Ukrainian military remains outnumbered.

Columns are getting close to the capital Kyiv, and as we heard earlier, the city of Mariupol on the Black Sea has been under siege for days.
