Ukraine has launched a large-scale long-range drone attack targeting several regions in Russia including the huge Ryazan oil refinery, after three days of massive strikes by Moscow against Ukraine.

Kyiv’s attack on Friday followed a series of drone and missile attacks on Ukraine, including on the capital, Kyiv, where a cruise missile hit an apartment block on Thursday, killing 24 people including three children.
