An American F-15E fighter jet crashed in Libya overnight and one crew member has been recovered while the other is “in the process of recovery,” according to a spokesman for the American military’s Africa Command and a British reporter who saw the wreckage.

The crash was likely caused by mechanical failure and not hostile fire, the spokesman, Vince Crawley, told Reuters. Details of the incident remained sparse. The crash was the first known setback for the international coalition attacking Col. Muammar el-Qaddafi’s forces in three days of strikes authorized by the United Nations Security Council…

United States military commanders repeated throughout the day that they were not communicating with Libyan rebels, even as a spokesman for the rebel military, Khaled El-Sayeh, asserted that rebel officers had been providing the allies with coordinates for their airstrikes. “We give them the coordinates, and we give them the location that needs to be bombed,” Mr. Sayeh told reporters.
