Ukraine's military claims to have destroyed another Russian warplane.
The Kyiv Post cited the General Staff of Ukraine's armed forces as saying the Su 34 fighter bomber was downed yesterday over the eastern Luhansk region.
It gave no further details and Russia has not commented on the claim.
The Su 34 is Russia's most advanced fighter bomber, but it has lost several of the warplanes to Ukrainian attacks.
Kyiv claimed Ukrainian forces shot down three of the aircraft in the south of the country in December.
