Three American citizens and one American green-card holder were released from Russian custody on Thursday as part of a massive swap of political prisoners involving the United States and Russia.

Wall Street Journal reporter Evan Gershkovich, former U.S. Marine Paul Whelan and fellow American Alsu Kurmasheva were among those released as well as Vladimir Kara-Murza. The multinational exchange is the biggest U.S.-Russia prisoner swap since the Cold War.

President Biden called the prisoner swap deal with Russia a "feat of diplomacy."

There have been a number of other U.S.-Russia prisoner swaps over the years. Here's a look back at seven major prisoner exchanges and the details surrounding them. 

December 2022 

Prior to Aug. 1, 2024, the last major prisoner exchange took place on Dec. 8, 2022, when WNBA star Brittney Griner was swapped for convicted Russian arms dealer Viktor Bout, the "Merchant of Death," as Fox News Digital reported at the time. 

Griner, who had been playing basketball in Russia during the off-season, was arrested by Russian authorities on Feb. 17, 2022, after less than a gram of hash oil was found in her luggage. She pleaded guilty and was sentenced to nine years in prison.

Bout was arrested in Thailand in 2008 and extradited to the U.S., where he was convicted of terrorism-related charges and sentenced to 25 years in prison in 2012.

The exchange took place at Al Bateen Executive Airport in Abu Dhabi, United Arab Emirates, as Reuters and others reported. 

April 2022

Earlier that same year, U.S. Marine veteran Trevor Reed was released from Russian custody on April 27, 2022, in exchange for Konstantin Yaroshenko.

Reed was arrested in Russia in 2019, accused of attacking a police officer, and was later sentenced to nine years in prison, as Fox News Digital reported earlier. 

Reed's family maintained his innocence and the U.S. government described him as unjustly detained.

His release was brokered as part of a one-for-one prisoner exchange for Yaroshenko, a Russian pilot who was sentenced to 20 years in a U.S. prison for smuggling cocaine into the country, Reuters reported.

July 2010

Ten Russian sleeper agents detained in the U.S. as part of the so-called "Illegals Program" were exchanged for four prisoners held in Russia.

One of the freed Russian prisoners was Sergei Skripal, who was convicted of high treason for working as a double agent for the United Kingdom, Reuters said. 

The swap took place on July 9, 2010, on the tarmac at Vienna International Airport in Austria.

September 1986

The second of two prisoner exchanges in the year 1986 came after U.S. News & World Report correspondent Nicholas Daniloff was arrested on Sept. 2 and accused of espionage by the KGB.

Daniloff, who claimed he had been framed, was held for less than a month before he was allowed to leave the Soviet Union on Sept. 23 without facing charges.

The U.S. believed Daniloff's arrest was in retaliation for the recent capture of Gennadi Zakharov, a Soviet citizen employed at the United Nations in New York City.

Zakharov pleaded no contest and was allowed to leave the U.S.

Also released was Soviet dissident Yuri Orlov, chairman of the Moscow Helsinki Group who spent nine years in prison and internal exile for documenting his country's violations of the human rights provisions of the Helsinki accords, according to Reuters. 

February 1986

Natan Sharansky was the first political prisoner released by then-Soviet leader Mikhail Gorbachev on Feb. 11, 1986.

Sharansky was accused of being a U.S. spy. He spent nine years in prison.

June 1985

Polish former intelligence officer Marian Zacharski was swapped alongside three other Soviet agents in exchange for 23 Americans held for espionage in Eastern Europe on June 12, 1985.

Zacharaski was arrested in 1981 and convicted of espionage.
