Ukraine is reportedly prepared to launch British long-range missiles at Russian positions in annexed Crimea, which would signal a significant escalation of western involvement in the conflict.
The announcement comes as Ukrainian forces prepare for the threat of a large-scale offensive from Russian troops over the coming days.
A Ukrainian military official has warned that Putin's forces have amassed 1,800 tanks, 3,950 armoured vehicles, 2,700 artillery systems, 810 Soviet-era multiple-rocket-launch systems, 400 fighter jets and 300 helicopters in preparation for "a new wave of attacks", according to Foreign Policy.
