KYIV (Reuters) - Two Ukrainian airlines disclosed problems in securing insurance for some of their flights on Monday while foreign carriers began avoiding the country's airspace as Russia masses a huge military force on its border.

Russia and Ukraine both hinted at fresh diplomatic efforts to avoid conflict on Monday, but Ukraine's biggest airline said its insurers had already terminated cover for at least some of its aircraft on flights inside Ukrainian airspace.
