Austria finds itself embroiled in a burgeoning espionage scandal with connections to Bulgaria, as suspicions of Russian espionage within the Federal Office for Internal Security continue to mount.

Austria's Chancellor, Karl Nehammer, has summoned the National Security Council amidst mounting suspicions of espionage involving former high-ranking security service officials allegedly spying for Russia.

At the Old Bailey court, five out of the six Bulgarians accused of espionage in the United Kingdom pleaded not guilty to charges of participating in a spy network allegedly operating on behalf of Russia. The group is accused of acting under the instructions of Austrian national Jan Marsalek, who is wanted for his involvement in a major financial fraud scheme.

British authorities have announced the arrest of a sixth Bulgarian man suspected of involvement in a Russian spy network operating within the United Kingdom. Tihomir Ivanov Ivanchev, 38, from Acton, West London, faces charges of conspiracy to commit espionage, according to statements released by British police on Tuesday.
