Vladimir Putin has agreed to share nuclear-ready missiles with Belarus in a chilling TV pledge.
The warmongering Russian President said Russia's Iskander-M systems are able to use normal and more deadly weapons.
In a chilling broadcast he said they "can fire ballistic and cruise missiles, both conventional and nuclear types".
The Kremlin claims they are able to reach a distance of up to 500km (310 miles).
Missiles have become a means of threatening the West since relations with Russia have worsened after Putin's invasion Ukraine by Russian forces on February 24.
The Russian president has referenced nuclear weapons on several occasions which many have seen as a warning about getting involved in the war between Russia and Ukraine.
He said Russia would assist in modifying Belarusian SU-25 warplanes to carry nuclear weapons in response Belarusian president Alexander Lukashenko.
In a televised broadcast Putin said: "We have made a decision: within the next few months we will hand over to Belarus the Iskander-M tactical missile systems."
Ukraine said enemy forces had "fully occupied" Severodonetsk, after weeks fighting between Ukraine and Russian troops.
It means Russia controls most of the Luhansk region pus nearby Donetsk in the Donbas region.
Ukrainian President Volodymyr Zelensky vowed to take back "all our cities" in a video address on Saturday night.
He admitted the war had reached an emotionally difficult stage and was uncertain many more losses would be endured.
A series of missiles targeted the north and west of Ukraine killing at least three, but local officials said there may be more people underneath debris in Sarny west of Kyiv.
Ukraine claimed some missiles came from Belarus which has given logistical support to Russia but is not involved in the fighting,
The strikes were part of Kremlin efforts to draw Belarus into the war, Ukraine claimed.
Severodonetsk's capture comes ahead of a period of Western diplomacy which will see US President Joe Biden flying to Germany for a G7 summit before talks with Nato.
It will involve a week of talks to try and prevent the war escalating further as it moves into a new period.
Earlier today The Mirror told how one person died and five more were left injured as Kyiv came under fire from Russian troops for the first time in three weeks.
The missile strikes, rained down on a kindergarten in the capital city early this morning before rescue crews pulled women and children, including a seven year old girl, from the rubble.
It is the first attack by Vladimir Putin's forces on Kyiv since June 5.
Several blasts rang through the city at around 6.30am as fire crews battled flames and rescued civilians from a nine-storey apartment building in the central Shevchenkivskiy district.
Debris was strewn over parked cars outside a smouldering building with a crater in its roof while a private kindergarten had smashed windows and a large blast crater by a playground about 400 metres away, Reuters said.
"They (rescuers) have pulled out a seven-year-old girl. She is alive. Now they're trying to rescue her mother," Kyiv's mayor Vitali Klitschko said.
