KYIV (Reuters) - Powerful explosions were heard in Kyiv early on Tuesday, Reuters witnesses and local media reported, with Ukraine's air defence forces saying all of the country was under the threat of a Russian ballistic weapons attack.

It was not clear whether the explosions were air defence systems in operation or air weapons hitting their targets.
