KYIV - Ukrainian military intelligence said Kyiv was not asked to ensure air space security on Jan 24 around the Belgorod area in southern Russia as had been the case during previous prisoner of war (PoW) swops with Moscow.

In a post on Telegram, it said Russia's accusations that Kyiv on Jan 24 shot down a military transport plane in the Belgorod area carrying 65 Ukrainian PoWs to a prisoner exchange could be "a planned action to destabilise the situation in Ukraine and weaken international support for our state".

The agency also said it had no reliable information on who was onboard the crashed Russian military transport plane.

Video posted on Telegram by Baza, a channel linked to Russian security services, and verified by Reuters, showed a large aircraft falling towards the ground near the village of Yablonovo in the Belgorod region and exploding in a fireball.

Russia said 74 people in all died, including six Russian crew members and three Russian soldiers.

In its statement on Telegram, the Ukrainian military intelligence agency said a swop of Ukrainian and Russian prisoners of war was indeed planned and Kyiv had met all the terms, but it was not informed by Russia about the number of planes carrying prisoners and their routes.

"At the same time, the Ukrainian side was not informed about the need to ensure the security of the air space in the area of the city of Belgorod at a certain period of time, as has been repeatedly done in the past," the agency added. REUTERS
