Two days before Russian forces began the operation to seize Crimea, somebody threw two Molotov cocktails through the window of Black Sea TV.

"It was a warning to us, so that we would stop," recalls Alexandra Kvitko, editor-in-chief of the only independent television station in the southern Ukrainian region. "But we continued."

Less than a week later, with Russian troops fully in control of the peninsula, Black Sea TV was cut off from broadcasting on Monday. It still reaches cable and satellite viewers — Kvitko estimates less than a third of its normal audience — but on Tuesday the authorities cut off the power.
