CRAWFORD, Texas, Aug 15 (Reuters) - President George W. Bush said Russia's actions were "completely unacceptable" in Georgia and that Moscow must end the crisis.

"The world has watched with alarm as Russia invaded a sovereign neighboring state and threatened a democratic government elected by its people," Bush said in his weekly Saturday radio address, which the White House released on Friday.

"This act is completely unacceptable to the free nations of the world," Bush said.

It was Bush's second statement on the Georgia crisis on Friday, a sign of U.S. concern about Russia's intentions. Moscow sent troops into Georgia in response to Tbilisi sending forces to retake South Ossetia, a pro-Russian province, last week.

Bush said he would send Secretary of State Condoleezza Rice to Brussels next week to meet with NATO foreign ministers and European Union officials.

Rice visited Tbilisi and France, which brokered a ceasefire, this week and was headed to Crawford, Texas, to meet with Bush at his ranch this weekend.

"To begin to repair the damage to its relations with the United States, Europe and other nations, and to begin restoring its place in the world, Russia must act to end this crisis," Bush said. (Reporting by Tabassum Zakaria; Editing by Kristin Roberts)
