We are pausing our live coverage of Russia's invasion of Ukraine.
Today, Russia threatened to target NATO nuclear weapons and facilities if they were deployed in Poland.
Deputy foreign minister Sergey Ryabkov told the state-run TASS news agency that joint NATO nuclear missions near the Russian border would be considered a threat to its security.
"Let alone permanent deployment [that] hotheads in Warsaw are speaking about," he adds.
It followed Poland's president saying this week that "we are ready" to host the nuclear weapons of NATO allies in response to Russia moving its own to neighbouring Belarus.
Ukraine fires US missiles for first time
Meanwhile, Sky's partner network NBC News reports that Ukraine has already used long-range ballistic missiles from the US against Russia twice this month.
The Army Tactical Missile System - dubbed ATACMS – was used twice against Russian forces in occupied Crimea and Ukraine.
But Russia's US ambassador Anatoly Antonov said the transfer of ATACMS was "impossible to justify," and added: "Aren't local politicians afraid of drowning in the quagmire of conflict?
"Washington will not be able to get out of the horrible swamp that has absorbed the blood of ordinary soldiers."
Belarus calls for peace
Belarus' Aleksandr Lukashenko said conditions for peace talks between Russia and Ukraine are "ripe," but warned the risk of military incidents with Kyiv was "quite high".
He claimed that about 120,000 Ukrainian servicemen are stationed on the border between Ukraine and Belarus.
His comments came hours before Belarus claimed - without evidence - that it stopped an attack on Minsk by drones that were launched from Lithuania.
