Poles are posting photos of themselves with apples online along with mocking comments to protest a Russian ban on Polish food.

Russia will begin banning imports of most fruit and vegetables from Poland on Friday for what it says are violations of health regulations and documentation procedures for some Polish produce.

Warsaw, however, says the ban is retaliation for its support of the latest round of European Union sanctions against Russia over Ukraine.

The ban is expected to mostly affect Polish apples. Poland is Europe's largest producer of apples, with more than half of its production going to Russia.

The daily Puls Biznesu, called Wednesday for a show of support with apple producers, and people responded with humorous posts on Twitter under the hashtag #jedzjablka — Polish for "eat apples."
