Russia has warned of the “real” threat of World War III breaking out.
The warning came through Moscow’s Foreign Minister Sergei Lavrov.
He was speaking ahead of a meeting between the United States and allies about plans to send further weapons to Ukraine.
Neighbouring countries have already sent a huge amount of weapons to Ukraine to help defend the country from the ongoing Russian invasion.
But they have not gone any further over fears that Russia may respond with a nuclear strike.
However, Mr Lavrov last night warned the risk of a World War III “is serious” and criticised Kyiv’s approach to struggling peace talks.
“It is real, you can’t underestimate it,” Mr Lavrov said.
For months, Ukrainian President Volodymyr Zelensky has been asking Ukraine’s Western allies for heavy weapons – including artillery and fighter jets – vowing his forces could turn the tide of the war with more firepower.
The calls appear to be resonating now, with a host of NATO countries pledging to provide a range of heavy weapons and equipment, despite protests from Moscow.
In a landmark trip to Kyiv over the weekend, Pentagon chief Lloyd Austin and Secretary of State Antony Blinken met Mr Zelensky and promised $700 million in new aid to Ukraine.
