2:23pm: 'Not a single reason' to lift Russia Olympics ban, say Poland, Ukraine, Baltics
Poland, Ukraine and the Baltic states reiterated on Monday their call to maintain the ban on Russian and Belarusian athletes at the Olympics, saying "not a single reason" existed to lift the restrictions.
"There exists not a single reason to move away from the exclusion regime for Russian and Belarusian athletes set by the IOC (International Olympic Committee) more than a year ago," Poland, Lithuania, Latvia and Estonia said in a statement co-signed by Ukraine.
The joint stance was published by the foreign ministries on the eve of the IOC executive board meeting in Lausanne beginning Tuesday, where the issue of Russian athletes will be discussed.
"We strongly believe that now is not the time to consider the opening up of a pathway for Russian and Belarusian athletes to return to the Olympic Games in any status," the statement said.
"We strongly urge it (the IOC) to reconsider its plans," the ministries added.
1:20pm: Ukraine withdraws city workers from frontline town Avdiivka
Municipal workers are being evacuated from the frontline town of Avdiivka in the eastern Donetsk region, said a Ukrainian official.
"It's a shame to admit, but Avdiivka looks more and more like a scene from post-apocalyptic movies," the head of the town's administration Vitalii Barabash said on social media.
"Therefore, a difficult decision was made to evacuate ... municipal workers, who at least somehow tried to maintain the cleanliness and vitality of the city."
Russian forces have been working to capture the entire eastern Donetsk region for several months, with the focus of fighting centring on Bakhmut, north of Avdiivka.

The Kremlin has said Russia will establish which state or states were behind blasts that damaged the Nord Stream gas pipelines and would do everything to stop what it called Western efforts to "cover-up" what happened.
The pipelines, which connect Russia and Germany under the Baltic Sea, were hit by unexplained blasts last September in what Moscow called an act of international terrorism.
President Vladimir Putin has said he believes the US was behind the blasts, an idea Washington has dismissed as false.

The secretary of Russia's Security Council, Nikolai Patrushev, said that NATO countries are a party to the conflict in Ukraine, according to excerpts from an interview with Russian government newspaper Rossiyskaya Gazeta on Monday.
Rossiyskaya Gazeta cited Patrushev as saying: "In fact, NATO countries are a party to the conflict. They made Ukraine one big military camp. They send weapons and ammunition to the Ukrainian troops, provide them with intelligence."
Patrushev, a former chief of the FSB internal security service, is widely seen as one of the most hawkish members of Russian President Vladimir Putin's inner circle.
6:45am: Ukraine wants 'effective' UN action to counter Russian 'nuclear blackmail'
Kyiv said on Sunday it was seeking an emergency meeting of the United Nation's Security Council to counter Russia's "nuclear blackmail" after President Vladimir Putin announced his country would station tactical nuclear arms in Belarus.
Putin said the deployment was similar to moves from the United States, which stores such weapons in bases across Belgium, Germany, Italy, the Netherlands and Turkey, an analogy western allies called "misleading".
"Ukraine expects effective actions to counteract the Kremlin's nuclear blackmail from the United Kingdom, China, the United States and France," the Ukrainian foreign ministry said.
"We demand that an extraordinary meeting of the UN Security Council be immediately convened for this purpose," it added.
