Russian authorities have imposed a ban on the import of tangerines from Abkhazia, a region under occupation, following the discovery of a harmful fly by Russian sanitary services. However, the Abkhaz side has not found any harmful insects in the citrus fruits. The situation is exacerbated by a political crisis in the region, triggered by mass protests against an investment agreement with Russia which led to the resignation of the self-proclaimed President Aslan Bzhania, and the refusal of the Abkhazian parliament to ratify the agreement.
