Ukraine crisis: Protesters in Kiev remain in square

Pro-Russian separatists in several Ukrainian cities are refusing to leave buildings, defying part of an international deal to help de-escalate the ongoing crisis.

The protesters insisted that pro-European Union demonstrators in Kiev's Maidan Square also had to pack up their camp.

The US has threatened tougher economic sanctions if Russia fails to abide by the international agreement to help de-escalate the crisis.

David Stern reports from Maidan Square.
