KYIV, April 20 (Reuters) - A number of Ukrainian servicemen have been accused of treason for giving away information during an unauthorised mission that enabled Russia to attack a military airfield, Ukraine's SBU security agency said on Thursday.
The SBU said in a statement that the servicemen had attempted, "without coordination with the relevant state authorities", to seize a Russian plane last July after its pilot said he would defect.
The SBU did not say how many service personnel were involved, or identify them, but said they were accused of treason and abuse of their position.
"These actions of individual servicemen, which led to serious consequences, death and injury of Ukraine's defenders and harmed the country's defence capabilities, require an appropriate legal assessment."
Russia, which invaded Ukraine in February last year, did not comment on the SBU statement.
