The next 24 hours in Ukraine could decide the fate of a two-month long protest in the capital city of Kiev.
The AP reported that opposition leader Arseniy Yatsenyuk has given Ukraine's president, Viktor Yanukovych, an ultimatum: fix the crisis or else.
"Tomorrow we will go forward together," he told to a crowd of thousands. "And if it's a bullet in the forehead, then it's a bullet in the forehead, but in an honest, fair and brave way."
We reached the BBC's David Stern in Kiev. He told us that while every day appears to be the decisive day, Thursday could really be the day.
"Do they win or do they lose?" he told us by phone. Stern didn't mince words. He said civil war could happen.
One protester and political scientist Kateryna Kruk says the situation is very tense.
"Everything is starting to escalate," she says. "[The government] is turning Ukraine into a dictatorship."
