MOSCOW—An American citizen has been arrested in Moscow on suspicion of espionage, Russia’s domestic security service, the FSB, said on Monday.
“On December 28, staff members of the Russian Federal Security Service detained U.S. citizen Paul Whelan in Moscow while on a spy mission,” the FSB said in a statement on its website. No other details were given.
The arrest of the U.S. citizen comes as tensions between Washington and Moscow continue to escalate over a range of issues from election meddling to the crises in Syria and Ukraine.
Earlier this month, Russian gun rights activist Maria Butina pleaded guilty to conspiring with a senior Russian official to infiltrate U.S. conservatives. Butina, 30, is the first Russian national to be convicted of seeking to influence U.S. policy in the run-up to the 2016 election by acting as a foreign agent.
