The prosecutor general for Russian-occupied Crimea says security services are pressing charges against a Crimean journalist for undermining Russia's territorial integrity.

Shortly after Russia annexed Crimea from Ukraine in March 2014, the parliament passed a law making it a criminal offense to question Russia's territorial integrity, which also means opposing the occupation.

The prosecutor general's office said in a statement on Tuesday that the Federal Security Service is pressing charges against an unidentified journalist for reports where he or she "called for the isolation of the peninsula." This could be the first criminal case for denouncing the occupation.

Independent media have been virtually banned in Crimea since the annexation and the few reporters who work for independent media outlets use pen names to hide their identities.
