Turkey has issued a travel warning urging its nationals to delay non-urgent and unnecessary travel to Russia.

Turkey's Foreign Ministry said Saturday it was issuing the warning because Turkish travelers were facing "problems" in Russia.

It said Turks should delay travel plans until "the situation becomes clear."

Turkey's downing of the Russian military jet Tuesday, the first time in half a century that a NATO member shot down a Russian plane, has drawn a harsh response from Moscow.

Russia has since restricted tourist travel, left Turkish trucks stranded at the border, confiscated large quantities of Turkish food imports and started preparing a raft of broader economic sanctions.
