Zelensky agrees to talks Monday as Putin raises nuclear alert and West adds sanctions

South Korea’s capital has joined a number of cities around the world lighting monuments in blue and yellow in support of Ukraine, reflecting the colors of its national flag.

Four landmarks in Seoul — the City Hall, Namsan Seoul Tower, Sebitseom on the Han River and Seoullo Media Canvas — were lit up on Monday.

Meanwhile, Ukrainians and supporters protested against the Russian invasion outside Moscow’s embassy in Seoul on Sunday and Monday.

New York’s Empire State Building was also lit up blue and yellow last week, with crowds gathering in Times Square on Saturday to protest the Russian invasion.

One protester, Olga Ladygima, told CNN she hadn’t slept for the past three nights. She is from the Ukrainian capital Kyiv, she said — and her friends in Ukraine have stayed up too, making homemade bombs to try to stop Russian tanks.

Approximately 100,000 people in Germany’s capital, Berlin, attended a protest this weekend against the invasion, police told CNN.

Crowds walked between the Russian embassy, Brandenburg Gate and the Victory Column on Sunday wearing blue and yellow, and holding up signs showing solidarity with Ukraine.
