Western Intelligence officials are warning that a new Russian offensive – that rivals the size and scale of the initial invasion last February – could be underway
Russia is targeting dozens of places each day, increasing its barrage of artillery attacks.
Ukrainian forces are struggling to hold their ground on a 230km stretch in the east.
Fighting is concentrated around the city of Bakhmut, where Russian forces have been slowly closing in on supply lines.
Kyiv says troops are awaiting tanks and other weapons systems from NATO countries, to give them the boost they need.
Ukrainian intelligence estimates that Russia now has more than 320,000 soldiers in the country – almost twice the size of Moscow’s initial invasion force.
Outside of Ukraine’s borders, it is estimated that Moscow also has 150,000-250,000 troops in reserve, either training or being positioned inside Russia to join the fight at any time.
