It looks like the crackdown on the opposition in Ukraine is in full swing. One by one this morning, the independent websites and live streaming sources were closed by Special Forces intervention and/or internet blocking attacks. Cell phones and other services also seem to be down in Kiev.
The main square in Kieve is still occupied by protesters but major concentrations of police and Special Forces are nearby.
ActivistWorld TV still seems to be up, and I assume it is live. Worth watching.
