Today will be the most difficult day, warns Ukrainian interior ministry adviser Anton Herashchenko, who says Russia is trying to break through to Kyiv with tank columns descending on the capital from the north-east and north-west.

And a source in Ukrainian counter-intelligence has told Ukrainska Pravda website details of Russia’s plan to take control of the city to take control of the country. It’s all unconfirmed but this is what they report Russia wants to do:

Seize a major Kyiv airport and air traffic control to allow 10,000 troops to land, distracting the military with attacks on the border

Sabotage Kyiv’s electricity and communications to cause panic

Provoke an exodus of refugees to prevent Ukrainian armed forces moving around

Seize government buildings including cabinet and parliament and capture the state leadership, forcing them to sign an agreement on Russian terms

Bring in pro-Russian leaders and split Ukraine into two parts, like East and West Germany
