Bulgarian Prime Minister Boyko Borisov is employing a Cosa Nostra scenario, according to Yane Yanev, leader of the marginal conservative party RZS, commenting on Thursday's explosion at the office of the Galeria weekly.

The blast that occurred before the office of the Galeria weekly early Thursday morning did not hurt any people. The Galeria weekly is a controversial newspaper known to the be mouthpiece of Aleksei Petrov, a former secret agent of the Bulgarian State National Security Agency DANS, who in February 2010 was arrested in a much advertised special police operation "Octopus" but the organized crime charges against him have been downsized ever since.

In January 2011, the Galeria weekly caused "Tapegate", a scandal that shook the Borisov Cabinet, by releasing tapped conversations of senior Bulgarian government officials providing discrediting information regarding the Borisov government. The tapes are believed to have been sneaked out of DANS or the Interior Ministry but their authenticity remains disputed.

RZS is also believed to have certain connections with Aleksei Petrov, and in January the RZS leader Yane Yanev contributed to the Tapegate by releasing himself several tapes of discrediting conversations of government officials. The exact relations between the RZS party and the Galeria weekly, however, are unclear.

Speaking Thursday afternoon, however, Yanev attacked vigorously Borisov declaring that he was running the state like a mafia organization and using Interior Minister Tsvetan Tsvetanov as a "suicide bomber" that he will scrap later.

According to the RZS party, the Galeria explosion is an "unprecedented terrorist attack" on part of Borisov designed to intimidate his opponents. Earlier, however, Borisov himself hinted he believed the people around Galeria, RZS, and Aleksei Petrov staged the bomb blast to simulate intimidation.
