Ballistic missile launch necessary to make Russia's voice heard, minister says
Russia used a powerful new missile against Ukraine in order to make Moscow's voice heard, deputy Russian foreign ministerSergei Ryabkov has said, according to state media.
Russian forces fired the intermediate-range Oreshnik missile into Ukrainian territory for the first-time last Thursday. Vladimir Putin said it was in response to Kyiv's use of US and British long-range missiles against Russia.
The RIA news agency cited Ryabkov as saying although Moscow does not think the time for negotiations with the West has passed, it needed to use stronger methods to get its point heard clearly.
Some experts believe Putin's new missile strike on Ukraine pointed to sabre-rattling by the Russian president.
Independent nuclear weapons expert Stephen Schwartz told Axiosthat Putin is "running out of things to do, apart from puffing up his chest and making a lot of noise".
"He's done and said any number of things, and they have not stopped what the United States and NATO and Ukraine are doing," he said.

South Korean leader calls for response to North Korea-Russia cooperation in Ukraine meeting
We've more detail to bring you now on the meeting between South Korea's president and a Ukrainian envoy in Seoul today.
Yoon Suk Yeol expressed hope that the two countries would work out effective ways to tackle the security threat posed by military cooperation between North Korea and Russia, according to a statement released by his office.
Pyongyang recently dispatched around 10,000 soldiers to join Russian forces in combat against Ukraine.
The Ukrainian delegation, led by defence minister Rustem Umerov, also met separately with South Korea's national security adviser Shink Wonsik, and its defence minister Kim Yong Hyun.
During the meetings, Umerov gave an update on the status of the conflict and said he hoped Kyiv and Seoul would strengthen their cooperation.
A statement said the two sides had agreed to continue sharing information on North Korea troops in Russia and any weapons transfers between the two countries.
Russia 'using bomber jets transferred from Ukraine in 1999'
Russia is still using at least six bomber jets it received from Ukraine 25 years ago, a Ukrainian media outlet has claimed.
Journalists at Radio Free Europe/Radio Liberty say an investigation revealed the Tu-160 strategic bombers are in active service with the Russian army.
The jets were handed over in 1999 in exchange for clearing Ukraine's debt for imported Russian gas, the outlet said.
The outlet said Ukraine's GUR military intelligence agency provided serial numbers of the bombers in service in Russia, which were compared to aviation records and registries.
Sky News cannot independently verify the report.
In pictures: Remains of ballistic missile fired at Dnipro
Pictures of the ballistic missile that Russia used in a strike towards the city of Dnipro this week have been released.
Components of the missile - which prompted international outcry - were shown to a photographer at an undisclosed location.
In the pictures, an investigator of the State Security Service of Ukraine gestures to the various burnt parts of what Kyiv says is the missile.
There was discussion among global observers on whether the projectile fired at Dnipro was an intercontinental ballistic missile.
Russian forces capture another settlement
Russia has taken control of another settlement in eastern Ukraine, its defence ministry has said.
Kremlin forces captured Nova Illinka in the Donetsk region, according to the state-owned TASS news agency.
The settlement is close to the embattled town of Kurakhove, which has been an objective for Russia as its forces accelerate their advance in eastern Ukraine.
Some observers believe that if defences around Kurakhove fall then Vladimir Putin's military will be able to push towards the city of Zaporizhzhia and also swing towards Pokrovsk.
Sky News was not immediately able to verify claims of battlefield advances.
South Korea's president meets Ukrainian envoy
Yoon Suk Yeol, the president of South Korea, has met with a Ukrainian envoy, his office has said.
Ukrainian defence minister Rustem Umerov is visiting South Korea to ask for weapons aid as his country continues to fight the Russian invasion, according to reports.
There has been renewed interest in the possibility of South Korea sending lethal aid to Ukraine after reports that North Korean troops have been fighting alongside Russian soldiers in the war.

"We stand resolutely behind the Ukrainian people," she told Sophy Ridgewhen asked about the development.

No hope that Trump delivers peace deal, says former Ukrainian foreign minister
Former Ukrainian foreign minister Dmytro Kuleba says he has no hope that Donald Trump can deliver a peace deal.
In an interview with Politico, he said that he cannot see Vladimir Putin agreeing to a swift end to the war.
"Putin still believes he can snuff out Ukrainian statehood and crush Ukraine as an independent democracy, and he thinks he's one step away from exposing the West as weak," he said.
Mr Trump's vice president-elect, JD Vance, has suggested that any peace deal would likely involve Ukraine giving up territory to Russia.
But Mr Kuleba, who was foreign minister throughout the full-scale invasion until September, said it was inconceivable that Volodymyr Zelenskyy could accept this.
"The Russians keep the Donbas, they keep Crimea, no NATO membership. Can Zelenskyy sign? He cannot because of the constitution. And because it will be the end of Zelenskyy politically,” Kuleba said.
