Air raid sirens heard across most Ukraine: Reports

Air raid sirens were heard across most Ukrainian cities urging people to seek shelters, local media reports have said.

Sirens were heard in the capital city Kyiv, the western city of Lviv in Odessa, and Kharkiv, Cherkasy, as well as in the Sumy region in northeast of the country, a number of local Ukrainian media reported.

Russian forces appeared to be regrouping earlier for a possible assault on Kyiv, with satellite images showing them firing artillery as they closed in on Kyiv.
