Ukraine crisis: EU to adopt sanctions against Russia

The EU says new sanctions against Russia should be adopted shortly and take effect on Tuesday, despite a Kremlin warning of retaliation.

Russia has warned that it could block international flights through its airspace if the EU goes ahead with new measures over the Ukraine conflict.

The European Commission spokeswoman, Pia Ahrenkilde-Hansen, said the sanctions would be "reversible", depending on how the situation in Ukraine developed.
