KYIV, Jan 13 - Russian forces launched the year’s most intense wave of missile attacks on Ukraine early on Tuesday, killing four people and injuring several others, while emergency power cuts were imposed in Kyiv after damage to infrastructure.

Ukraine’s grid operator Ukrenergo said emergency power cuts were imposed in Kyiv after what the head of Kyiv's military administration, Tymur Tkachenko, said earlier was a short but intense missile attack on the capital.
