• A daily summary of global reports on security issues.

Both Washington and the Kremlin played down the diplomatic impact of Russia's detention of a US diplomat it suspects of being a CIA agent, suggesting that the incident will prove a minor episode in US-Russian relations.

Reuters reports that Dmitry Peskov, a spokesman for Russian President Vladimir Putin, said that the Ryan Fogle incident did not contribute to "strengthening mutual trust between Russia and the US," but Reuters notes that Mr. Peskov avoided inflammatory language. And BBC News writes that Russian Foreign Minister Sergei Lavrov did not address the incident during a meeting with US Secretary of State John Kerry in Sweden.

Similarly, Nikolai Kovalyov, a former Russian security chief and current parliamentarian for Putin's United Russia party, told independent Russian news agency Interfax that he did not believe Fogle's detention will affect US-Russian relations. "The Americans do nothing other secret services, including ours, would not do," he said.

Reuters notes that US State Department spokesman Patrick Ventrell also played down the impact of the Fogle arrest on US-Russian relations, saying "I'm not sure I would read too much into one incident one way or another."

Fogle was reportedly detained on Monday by Russian security on suspicion that he is a CIA agent trying to turn Russian agents. The FSB, Russia's CIA counterpart, claims that it caught Fogle red-handed, with "special technical devices, written instructions for the Russian citizen being recruited, a large sum of cash and means of changing his appearance." Fogle's image dominated the Russian media on Tuesday, which showed him in detention with a collection of wigs, sunglasses, money, and other paraphernalia he is alleged to have been carrying.

Fogle's alleged spy kit has struck many experts as too obviously cloak-and-dagger to be legitimate, however.

Former FBI counterintelligence officer Eric O'Neill told CNN that he "very much doubt[s] that a highly trained CIA operative is going to be walking the streets of Moscow wearing a really bad blonde wig. It's poor tradecraft, and looks like a setup to me," suggesting that the material was planted on Fogle for dramatic effect.

Mark Galeotti, a security and espionage expert at New York University told the Daily Telegraph that it's possible that Fogle is indeed a low-level CIA agent, but that the kit was added to "ice the cake."

Alexander Golts, a security analyst with the online newspaper Yezhednevny Zhurnal, told º£½Ç´óÉñ that "There are some peculiar aspects of this story as well, particularly the letter – which has been reproduced in the Russian press – promising this Russian $1 million per year for his cooperation. I really have trouble picturing what kind of information is worth that much money."

But Mr. Golts notes that spycraft is often stranger than fiction, citing Kremlin accusations in 2006 that Britain's MI6 was making use of a high-tech device disguised as a rock to spy on Russia – accusations that later proved to be true.

"Remember how we all laughed at the spy-rock story? But it turned out to be real enough, so we must admit that such things do happen," he says.
