Russia’s state aviation agency has officially banned any liquids in carry-on baggages for flights at all of the country’s airports. That step is believed to be taken as a safety measure ahead of next month’s Winter Olympics in Sochi.

      In the official statement published on Wednesday the Federal Air Transport Agency explained that decision by the threat of a terror attack on aircraft with the use of home-produced explosives.

      Two of Moscow’s international airports, Sheremetyevo and Vnukovo, said that they had already introduced the ban, which includes medicines and cosmetics, Russian media reported. Sheremetyevo airport also announces about including gels, paint and glue in the ban list.

      The agency found it significant to add that medicines and personal care items considered necessary to a passenger’s life and health would be exempt from the ban, provided they had been shown to airport security personnel and inspected.

      It is still not clear if the additional security measures will be temporary. At the same time, some Russian news agencies report that the new rules would be in force until March 21, when the Olympic and Paralympic Games will have ended.

      Previous rules allowed carrying 100 ml. of liquids in hand luggages at most. That limitation didn't apply to medicine and child nutrition.
