NewsNow Desk: There are countless citizens hiding under the streets of Kyiv and other Ukrainian cities as Russian rockets hit the country.
Some are sheltered in purpose-built bunkers, others in basements and large groups have gathered in underground railway stations.
Many metro stations are full of families and children, who have brought along everything from sleeping bags and blankets, to crossword puzzles and dogs.
“It just happened. We were not preparing to flee,” one sheltering resident said.
“Nobody believed that this war would start and that they would take Kyiv directly. I think most people are hoping that it will all be OK. I also hope so.”
Kyiv is home to the deepest train station in the world, Arsenalna Metro Station, while people are also sheltering in subways in cities such as Kharkiv, near Ukraine’s north-eastern border with Russia.
With the threat of invasion looming for weeks, residents of the capital had time to reacquaint themselves with the thousands of shelters scattered around the city.
Some were built during the Cold War and, while they may look antiquated, officials have been working to upgrade them since 2014, the year Russia annexed Crimea.
