The Obama administration secretly gave its blessing to arms shipments to Libyan rebels from Qatar last year, but American officials later grew alarmed as evidence grew that Qatar was turning some of the weapons over to Islamic militants, according to United States officials and foreign diplomats.
But after the White House decided to encourage Qatar — and on a smaller scale, the United Arab Emirates — to ship arms to the Libyans, President Obama complained in April 2011 to the emir of Qatar that his country was not coordinating its actions in Libya with the United States, the American officials said. “The president made the point to the emir that we needed transparency about what Qatar was doing in Libya,” said a former senior administration official who had been briefed on the matter.
