Life underground in Kyiv as air raid sirens ring

May 5 ------ An air raid alert was triggered in Kyiv earlier today, forcing many people to find shelter in the city's metro stations.

Ukraine's warning of a missile threat from Russia came shortly after Moscow accused Kyiv of being behind a purported attack on the Kremlin overnight. For residents in Ukraine's capital, air raid sirens are a familiar sound. Those who found shelter waited patiently underground for the threat to be lifted - with one teacher even conducting a foreign language lesson for students.
