Sec. of State John Kerry on Russia: The President "has all options on the table."

Secretary of State John Kerry said Russia's decision was a "brazen act of aggression" and that US President Barack Obama was "considering all options" before responding to the situation.

"This is not, or should not be East-West, Russia-United States, Russia versus Europe: this is about the people of Ukraine, people who stood up against snipers firing at them from the roofs, who are fighting against the tyranny of having political opposition put in jail," said Mr Kerry.

"And President Putin, I think, needs to think carefully about Russia's real interests here. You know Russia may be able to invade Crimea, but in the end, Russia will isolate itself," he added.
