Putin launches Russian invasion of Ukraine; UN security council meets

One week after Ukrainian strongman Viktor Yanukovuych fled Kiev and the government snipers who'd murdered dozens of protesters ran for the hills, Vladimir Putin has received approval from the Russian Parliament to invade the country. In Crimea, an area where armed gangs loyal to Yanukovuych have taken control, protesters have been beaten and been made to kneel. The Ukrainian navy has taken to sea. The Russian ambassador to the USA is said to be withdrawing. Russian tanks are in Crimea. The UN Security Council is meeting to discuss intervention.

Twitter's #russiainvadesukraine is a good place to stay abreast of affairs.
