Live updates: Ukraine-Russia border tensions

From CNN's Sharon BraithwaiteUnited Kingdom Defense Secretary Ben Wallace said Friday that he heard "clearly" from the Russian government that they had no intention of invading Ukraine.Speaking at a news conference in Moscow after talks with Russia's Defense Minister Sergei Shoigu amid Russia-West tensions over Ukraine, Wallace said: "I heard clearly from the Russian government that they had no intention of invading Ukraine."The UK will look at the actions that back up Russia's assurances that Moscow will not invade Ukraine, Wallace said."When they say to me they are not going to invade Ukraine, we will take that seriously, but as I also said we will look at the actions that accompany it," he said.Wallace also said that "the disposition of the Russian forces that we see over 100,000 in both Belarus and Ukraine, obviously gives that size of force the ability to do a whole range of actions including an invasion of neighboring country at any time."Wallace said that he had "constructive and frank discussions" with Shoigu, and that they both agreed on the importance of the implementation of the Minsk agreement as "a clear way forward.""We urged dialogue as a way through to address any concerns that Russia the Russian government may have," Wallace said.Wallace said he would put the level of UK-Russia relations "above zero" following his meeting with Shoigu Friday, after Russian state news agency RIA-Novosti earlier reported that Shoigu had told Wallace that the level is "close to zero.""Of course Britain has some ongoing issues with the Russian government, not least, the poisoning and deployment of nerve agent, by agents of the Russian state in Salisbury, and the requests we have, obviously, out for the people suspected of committing that crime. For this reason, the entire country of Ukraine has been raised to Level 4," the ministry said.The South Korean government raised its travel alert level for Ukraine to 4, the highest level, banning travel to Ukraine and ordering its nationals in the country to evacuate, according to a news release from the South Korean Ministry of Foreign Affairs Friday.The ministry said the level 4 alert comes into effect on Saturday 5 p.m. Ukraine time.The ministry said this is a preventive measure in case the local situation rapidly worsens in Ukraine.As of Friday, there are a total of 341 South Korean nationals in Ukraine, the release said.South Korea previously advised its nationals residing in Kyiv and 14 other Ukrainian oblasts to leave amid heightened tensions between Ukraine and Russia on Jan. 25.From CNN's Betsy Klein US President Biden is holding a call with other world leaders on the situation in Ukraine this morning, a White House official told CNN.The leaders of Canada, the United Kingdom, France, Germany, Italy, Poland, Romania, NATO, the European Commission, and the European Council will be on the call, according to the official.Please enable JavaScript for a better experience.
