A CIA spy has been arrested in Russia, according to Russian authorities. Russian security services announced Tuesday that they have arrested a CIA agent posing as an employee of the U.S. embassy in Moscow. The CIA agent was allegedly in a blond wig trying to recruit a Russian secret service agent to work for the U.S.

Ryan Fogle, the person who was arrested, was a third secretary at the U.S. Embassy in Moscow. Russia's Federal Security Service (FSB) said that Fogle was carrying disguises, special equipment, a large amount of cash, and written instructions. (Apparently, he forgot to eat or burn them.)

Russian state television also showed a letter it claims are instructions to the agent Fogle was attempting to recruit. The letter, typewritten in Russian, is addressed "Dear friend," and it offers $100,000 to "discuss your experience, expertise and cooperation" and up to $1 million per year for long-term cooperation. It includes instructions for accessing a secret Gmail account to communicate. It is signed "Your friends."

Authorities detained Fogle late Monday; the U.S. Embassy has declined to comment.

The FSB (the post-Soviet ear replacement for the KGB) is claiming that Fogle was attempting to recruit a Russian counterterrorism officer for the CIA to aid in investigation of the Boston Marathon bombings. The officer specializes in the Caucasus, a geographical region in southern Russia that includes Chechnya and Dagestan. The Tsarnaev brothers, suspects in the Boston Marathon bombings, are ethnic Chechens. Tamerlan Tsarnaev, the elder brother, spent six months in Dagestan last year.

Dagestan is currently gripped with militant Islamic violence. Russia and the U.S. have been publically working together to try to determine whether Tamerlan Tsarnaev had contacts with insurgents in Dagestan.

This is the first case of an American diplomat being publically accused of spying in a decade or so. Current relations between Russia and the US are already tense; experts worry this will further strain them.

Because Fogle has diplomatic immunity, he was protected from arrest. After being detained and processed, he was handed back to the U.S. diplomats in Moscow and ordered to leave the country.  U.S. Ambassador to Russia Michael McFaul has been summoned to the Russian Foreign Ministry over the incident.
