Jeff Bezos flew on his personal jet to take home the Washington Post reporter detained by Iran

Jeff Bezos flew to Germany on his personal jet and then flew Jason Rezaian, a Washington Post reporter who was detained by Iran for 18 months, to the US, according to media reports.

Bezos, the CEO of Amazon, is also the owner of The Washington Post, which he purchased in 2013.

According to CNN, Bezos had dinner with the Rezaian family on Thursday evening in Germany and then flew Rezaian and his family back to the US on his private jet.

Rezaian is one of several Americans in prison in Iran who were freed last weekend, in a historic prisoner exchange between Iran and the US.

Rezaian, who was The Post's Tehran bureau chief, had been imprisoned in July 2014 on espionage charges, which he denied. After his release a few days ago, he flew to an American military hospital in Germany.

The Washington Post tweeted a picture of the pair in the jet on Friday.

Bezos has not yet publicly talked about about his role escorting Rezaian home on his jet, but tweeted about The Post's efforts to free Rezaian.
