WASHINGTON: Two Americans and the remains of a third held captive by Iranian-backed militants in Yemen were released on Wednesday in exchange for the return of about 250 of the Houthi rebels from Oman, according to the White House and sources in the region. Oman’s state news said the American captives were flown out of Yemen on an Omani plane. It said 250 “Yemeni brothers” who received treatment in Oman have been returned to Yemen’s capital, Sanaa, on two flights as part of the exchange. “The United States welcomes the release today of US citizens Sandra Loli and Mikael Gidada from Houthi custody in Yemen,” national security adviser Robert O’Brien said in a statement. “We send our condolences to the family of Bilal Fateen, whose remains will be repatriated as well.” O’Brien did not mention the exchange, but thanked the leaders of Oman and Saudi Arabia for their help in securing the release of the Americans. Kieran Ramsey, director of the administration’s hostage recovery cell, said Loli and Gidada would soon be on their way back to the United States. “Tragically, one of these Americans died during his unlawful captivity,” Ramsey said. Kash Patel, a deputy assistant to Trump who worked on the deal, told The Wall Street Journal that Loli had been held by the Houthis for about three years and Gidada was held captive for about a year.
