Russian forces partially occupy three suburbs of Kyiv as they look to encircle capital

Russian forces attempting to encircle Kyiv have partially occupied three north-western suburbs, as Ukrainian forces continued to defend the besieged city of Mariupol.

The Ukrainian army said in the early hours of Tuesday that it had forced Russian troops out of Makariv – a strategically important Kyiv suburb – after a fierce battle, retaking control of a key highway to prevent the invading forces from surrounding the capital from the northwest.

But Ukraine’s defence ministry said Russian forces advancing on the capital were able to partially take over Bucha, Hostomel and Irpin.

Ukrainian forces are still holding off Russian attempts to capture the southern port city of Mariupol – which on Monday refused to surrender.
