Sanctions force cancellation of Moscow air show.

Russia is likely to cancel this year's Moscow air show, which has been a major venue for showing off new warplanes and negotiating aerospace contracts, due to Western sanctions on Russia connected to the conflict in Ukraine that would shrink international participation and have affected parts supplies to manufacturers. Security concerns in the wake of drone attacks that hit the Kremlin and the outskirts of Moscow in May are also cited as a reason for the cancellation.
