Around 5am Ukrainian time, explosions were heard near major Ukrainian cities, including the capital Kyiv.
Explosions could be heard in the Ukrainian capital of Kyiv shortly after Mr Putin’s address, while explosions were also reported in the cities of Odesa and Kharkiv.
Ukraine’s border guard agency said the Russian military attacked the country from neighbouring Belarus.
Prime Minister Boris Johnson said Russian President Vladimir Putin has “chosen a path of bloodshed and destruction” with his attack on Ukraine and that the UK and its allies would respond “decisively” and following a Cobra meeting will be making a televised announcement.
It came as Ukraine’s president declared martial law, while Russia’s military said it had targeted Ukrainian air bases and other military assets and had not targeted populated areas.
