I think there’s a very high likelihood he’s fleeing. Both the Russians and US have confirmed he’s travelling. This from the WSJ article….

When they reached the presidential palace early Thursday morning, the French and German delegations were told President Viktor Yanukovych had moved to a different location for security concerns. After several hours crisscrossing the Ukrainian capital by car, the delegations eventually returned to the palace, where the president had resurfaced.

Yesterday he didn’t feel the country was secure enough to stay in his own house. I think it’s very unlikely he’s now leaving town for a business meeting.
