Vera Lytovchenko has become an internet icon of resilience as images of the concert violinist playing in the basement bomb shelter in Ukraine’s northeastern city of Kharkiv have inspired an international audience via social media.

The action follows pleas by Ukrainian President Volodymyr Zelenskyy to U.S. and Western officials to cut off the imports, which had been a glaring omission in the massive sanctions put in place on Russia over the invasion.

A third round of talks between the two sides ended with a top Ukrainian official saying there had been minor, unspecified progress toward establishing safe corridors that would allow civilians to escape the fighting. Russia’s top negotiator said he expects those corridors to start functioning Tuesday.

Food, water, medicine and almost all other supplies were in desperately short supply in the port city of Mariupol, where Russian and Ukrainian forces had agreed to an 11-hour cease-fire that would allow civilians and the wounded to be evacuated. But Russian attacks quickly closed the humanitarian corridor, Ukrainian officials said.

Maria and her fiancé, David, married Saturday before about 20 people in the backyard of an Oak Park home. On Monday, she plans to fly to Poland, then make her way to the Ukrainian border, ultimately aiming to volunteer to fight for her home country.

Even though the Zaporizhzhia nuclear plant is of a different design than Chernobyl and is protected from fire, nuclear safety experts and the International Atomic Energy Agency warn that waging war in and around such facilities presents extreme risks.

Russian troops Friday seized the biggest nuclear power plant in Europe after a middle-of-the-night attack that set it on fire and briefly raised worldwide fears of a catastrophe in the most chilling turn in Moscow’s invasion of Ukraine yet.

Moscow’s advance on Ukraine’s capital in the north has apparently stalled, with a huge armored column outside Kyiv at a standstill. And stiffer than expected resistance from the outmanned, outgunned Ukrainians has staved off the swift victory that Russia may have expected.

Russia reported its military casualties for the first time since the invasion began last week, saying nearly 500 of its troops had been killed and almost 1,600 wounded. Ukraine insisted Russia’s losses were far higher but did not immediately disclose its own casualties.

Russian forces stepped up their attacks on crowded urban areas Tuesday, bombarding the central square in Ukraine’s second-biggest city and Kyiv’s main TV tower in what the country’s president called a blatant campaign of terror.

Facing disquiet at home and danger abroad, President Joe Biden will deliver his first State of the Union address at a precipitous moment for the nation, aiming to navigate the country out of a pandemic, reboot his stalled domestic agenda and confront Russia’s aggression.

An embattled Ukraine moved to solidify its bond with the West on Monday by signing an application to join the European Union, while the first round of Ukraine-Russia talks aimed at ending the fighting concluded with no immediate agreements.

The directive to put Russia’s nuclear weapons in an increased state of readiness for launch raised fears that the crisis could boil over into nuclear warfare, whether by design or mistake.

With events rapidly unfolding on TV and across social media, child development experts urge parents to check in with children of all ages but not to worry if those conversations are brief.

With disinformation rife and social media amplifying military claims and counter-claims, determining exactly what is happening is difficult.

The chief of the NATO alliance said the “brutal act of war” shattered peace in Europe, joining a chorus of world leaders who decried the attack.
