An American cryptocurrency executive held in Nigeria for the past eight months has been released after authorities there announced they were ending his money laundering trial on health and diplomatic grounds. Tigran Gambaryan, Binance’s head of financial crime compliance, was freed on humanitarian parole and was returning to the United States to receive medical attention, White House national security adviser Jake Sullivan said in a statement Thursday announcing the release. “I am grateful to my Nigerian colleagues and partners for the productive discussions that have resulted in this step and look forward to working closely with them on the many areas of cooperation and collaboration critical to the bilateral partnership between our two countries,” Sullivan said.
