MOSCOW/KYIV (Reuters) - Russian mercenary boss Yevgeny Prigozhin said on Saturday his Wagner fighters had crossed the border into Russia from Ukraine and were prepared to go "all the way" against Moscow's military, hours after the Kremlin accused him of armed mutiny.

As a long-running standoff between Prigozhin and the military top brass appeared to come to a head, Russia's FSB security service opened a criminal case against him, TASS news agency said. It called on the Wagner private military company forces to ignore his orders and arrest him.
