US President Joe Biden has issued a warning to Russian President Putin.

Speaking to the media, the US President has said that if Russia invades Ukraine, it will be the largest invasion since World War II.

The US President has stated that if such an invasion takes place, personal sanctions may have to be imposed on the Russian President.

Meanwhile, Britain has warned of a plot to overthrow the pro-Moscow government in Ukraine.

The British Foreign Secretary has stated that Russian President Vladimir Putin is taking steps to use former Ukrainian parliamentarian Yvonne Murayev for this purpose.

The British Foreign Secretary said in a statement that Russia should end its aggression and misinformation-based actions and pursue a diplomatic course.

Russia has denied that it is planning an invasion, although it has deployed hundreds of thousands of troops near Ukraine’s border.
