This was stated by Advisor to the President of Ukraine Yurii Biriukov on his Facebook page, Censor.NET reports.
"Recent data on the Donetsk airport as of 3:30 p.m. We are clear on the "gas" issue. Firstly, there are a lot of smoke grenades - the separatists threw a lot of them to drag away the carcasses of their dead. Secondly, the plastic casing on the first floor caught fire, which added some hysterical stink. Information on chemical warfare gas is not true," Biriukov stated.
Also, according to him, as a result of today's attack on the airport there are casualties among the Ukrainian servicemen.
"Losses: 1"200th"(dead - ed.) / 11"300ths"(wounded - ed.)," he added.
