Russian forces seize two Ukrainian bases in Crimea

Sevastopol, Ukraine: The United States warned Moscow it was on a "dark path" to isolation on Wednesday as Russian troops seized two Ukrainian naval bases, including a headquarters in the Crimean port of Sevastopol where they raised their flag.

The dramatic seizure came as Russia and the West dug in for a long confrontation over Moscow's annexation of Crimea, with the United States and Europe groping for ways to increase pressure on a defiant Russian President Vladimir Putin.
