International observers were fired upon, on Saturday, as they attempted to enter Armyansk, Ukraine, in the Crimea region. The observers belonged to the Organisation for Security and Co-operation in Europe, or OSCE.
No one was hurt in the incident, but it was a clear warning that the controllers of Crimea will not allow international access. For now, the observers have fallen back, and are waiting for things to calm down before deciding to try again.
As many as thirty thousand Russian troops have crossed into Crimea, ensuring that Ukraine is unable to take the region back. Russia still denies that the troops are theirs, and they are unmarked, but they carry Russian equipment, speak Russian, and have been seen crossing the straight from Russia.
Inside Crimea, Ukrainian troops maintain positions on their bases, but are besieged by the unmarked Russian troops as well as pro Russian militias. In several cases the Ukrainian troops have been
harassed by Russian forces that Russia says aren't there.
Officials in the Crimea plan a referendum, to decide if they should join
Russia or not. However, the referendum has been deemed illegal by
Ukraine, the EU, and the UN.
Ukraine and the international community continue to speak out against this "invasion", demanding that Russia withdraw. However, other than sanctions nothing has been done or threatened. It seems that the world can not stop Russia from taking over Crimea, without going to war with Russia.
