Special counsel Robert Mueller's team is examining a series of previously unreported meetings that took place in 2017 in the Seychelles, an archipelago in the Indian Ocean, as part of its broader investigation into Russian meddling in the 2016 presidential election, according to two sources briefed on the investigation.

The sources said several of those meetings took place around the same time as another meeting in the Seychelles between Erik Prince, founder of the security company Blackwater, Kirill Dmitriev, the director of one of Russia's sovereign wealth funds, and Crown Prince Mohammed Bin Zayed Al-Nahyan, the effective ruler of the United Arab Emirates (also known as "MBZ"). Details of that earlier meeting were first reported by the Washington Post last year.

The sources requested to remain anonymous because they were not authorized to speak publicly about the matter.

The inquiry into the meetings in the Seychelles suggests there is growing interest on the Mueller team in whether foreign financing, specifically from Gulf states, has influenced President Trump and his administration.

The New York Times reported in March that Mueller's team questioned George Nader, a Lebanese-American businessman who helped broker the Seychelles meeting, about whether the Emiratis attempted to buy political influence in the White House.

Documents obtained by this reporter, and interviews with those familiar with the probe, suggest Mueller is also looking at other foreign influencers, including individuals from Russia and from Saudi Arabia.

The meetings in the Seychelles are a key component of Mueller's investigation, sources familiar with the investigation said. The meetings connect powerful players from Russia, the U.S., the UAE and Saudi Arabia across the political, financial and defense worlds. The details of what was discussed in the meetings in January and in the following months, however, are scarce.

Flight records and financial documents obtained by this reporter over twelve months, as well as interviews with parliamentary and aviation officials in the Seychelles, paint a scene out of a Hollywood thriller.

Wealthy and politically-connected individuals from across the globe -- from Russia, France, Saudi Arabia and South Africa -- land in the Seychelles for meetings that take place as a part of a larger gathering hosted by MBZ, according to an individual briefed on the matter, who also requested anonymity. Many of them fly in on private jets and several do not clear customs. Some check into the Four Seasons Hotel while others arrive and stay on their yachts.

Individuals connected to the Saudi financial system, including the Saudi Arabian Monetary Agency and the Arab National Bank, flew into the island the second week of January 2017, as did an aircraft purportedly owned by the former deputy minister of defense, Prince Khaled bin Sultan bin Abdulaziz, fight records show. Other individuals on those aircraft held passports from Egypt and Singapore.

Dmitriev flew into the Seychelles Jan. 11, 2017 with his wife Natalia Popova and another woman with the last name Boldovskaia. Six other Russian individuals flew to the island just a few days after Dmitriev. The aircraft's ownership is unclear but it flew between Russia, Geneva and Cyprus in 2017.

Others on the island included Alexander Mashkevitch, an alleged financier of Bayrock, an investment vehicle linked to Trump, and Sheikh Abdulrahman Khalid BinMahfouz, according to flight records. BinMahfouz's father, before his death, was a billionaire and the former chairman of Saudi Arabia's first private bank.

Nader travelled to Seychelles Jan. 7, 2017 and again on March 24 on an aircraft with the tail number VP-CZA, flight records show. The aircraft is registered to Gryphon Asset Management, an aviation consulting company based out of Dubai.

Nader is a well-known advisor to the UAE with links to Dmitriev and members of the Saudi Royal family. He has attended meetings at the White House with Stephen Bannon and Jared Kushner in the past, according to the Times, and has also been linked to Trump fundraiser and deputy finance chairman of the Republican National Committee Elliot Broidy.

The Associated Press reported last month Nader sent Broidy $2.5 million through a Canadian company. Broidy then began giving donations to members of Congress who were actively supporting legislation critical of Qatar, the AP reported.

The previously reported meeting in the Seychelles between Prince, Dmitriev and MBZ was described as an attempt by the U.S. to set up a backchannel with Russia. The Post reported that Blackwater founder Erik Prince, an informal adviser to the Trump team, acted as a representative of the administration in the meeting with an unnamed Russian individual.

Later, this reporter broke the news in The Intercept that Prince had met with Dmitriev -- the head of the sovereign wealth fund with close ties to Russian President Vladimir Putin. Prince admitted in a congressional testimony earlier this year that he had met Dmitriev on the island, but said it was a chance meeting.

Mueller's team has received evidence challenging Prince's testimony, according to an ABC News report.
