Russian warplane entered South Korean air defence zone, Seoul says

A Russian military plane entered South Korea's air defence zone on Thursday without prior notice, South Korea's defence ministry said.

Russian warplanes had gone into the Korean Air Defense Identification Zone eight times between March 11 and Thursday, according to the ministry. Moscow does not recognise South Korea's air defence zone.

South Korea's defence ministry said it had lodged a complaint with Russia's military attache over the incident.
