Russia is going to prepare wide-ranging economic sanctions against Turkey as it accused Turkey has downed one of its military jets on the border with Syria.
Prime Minister Dmitry Medvedev said the measures would be drafted within days, and could hit joint investment plans.
Also on Thursday, Russia’s military suspended all communication channels with the Turkish military, including a “hot line” to help avoid air accidents.
Turkey says the plane violated its airspace – charges Russia denies.
Russia has sent troops and aircraft to Syria to back up the Syrian government of Bashar al-Assad in the civil war.
