Ukraine: How a week of war has transformed lives
Seven days which sparked a burning patriotic resolve in Ukraine, which propelled people the world over, from presidents and prime ministers, bankers and business leaders, football stars to figure skaters, artists and activists, to stand up and be counted to condemn Russia's aggression.
The Russian rouble collapsed, the UN General Assembly called on Moscow to pull out; Russian leaders denounced this "Russiaphobic frenzy." And, on the ground, swathes of Europe's second-largest country were reduced to smoking ruins, a harrowing echo of Russia's blistering campaigns in Grozny and Aleppo.
In the days before Russia invaded Ukraine, Kyiv was a European city of golden-domed cathedrals gleaming in the night, brightly-lit restaurants serving steaming bowls of borsch, corner kiosks pouring coffee behind frosty winter windows.
And the world was a place where many thought a blitzkrieg across a border was only history's business. At the Munich Security Conference, many a government minister quietly told me "I just don't think it will happen". And, of course, not against the capital.

By 05:00, posts cascaded across the internet - "hearing thuds" in Kyiv, Kramatorsk, Melitopol, Chernobyl, Odessa. The list was long.
At 05:58, Ukraine's Foreign Minister Dmytro Kuleba tweeted "Putin has launched a full-scale invasion". Hours earlier, President Vladimir Putin had announced the start of a "special military operation" in eastern Ukraine.
At 06:00 Liana called her mother. "I told you so. Are you packed?"
