Russia has warned that it could block international flights through its airspace if the EU imposes new sanctions over Ukrainian conflict.
Russian Prime Minister Dmitry Medvedev warned that Moscow would respond "asymmetrically" to further sanctions, noting that Russian airspace ban "could drive many struggling airlines into bankruptcy", he told a Russian daily Vedomosti.
"If there are sanctions related to the energy sector, or further restrictions on Russia's financial sector, we will have to respond asymmetrically... For example, restrictions in the transport sector.
It comes after The Committee of Permanent Representatives at the EU Council last Friday agreed on a package of new strengthened sanctions on Russia due to its role in Ukrainian conflict.
Fighting in the east has killed some 2,600 people since April. The truce and roadmap to peace were agreed on Friday in Minsk.
Russia has repeatedly denied accusations by Ukraine and the West that it has been sending troops into Donetsk and Luhansk regions to help the rebels to fight Ukrainian army.
