Russia has declared an economic package sanctions against Turkey over the shooting down of a Russian warplane on the Syrian border on Tuesday.
A decree signed by President Vladimir Putin (in Russian) covers imports from Turkey, the work of Turkish companies in Russia and any Turkish nationals working for Russian companies.
The decree also calls for an end to charter flights between the countries.
Turkish President Recep Tayyip Erdogan has refused to apologise to Russia.
On Friday, he accused Moscow of “playing with fire” in its Syria operations. But on Saturday, he said he was “saddened” by the downing of the jet.
