International monitors from the Organization for Security and Cooperation in Europe, who are not investigators but have been observing the conflict, have so far been unsatisfied with the access they have received at the crash site. On Saturday, rebel guards would not let them approach the wreckage.
Borodai said the OSCE team wanted him to cut off journalist access to the site, but he declined to do so, claiming his interest in "freedom of the press."
Earlier in the day, the U.S. Embassy in Kiev provided the most detailed evidence thus far to prove the rebels shot the passenger plane down with a surface to air missile.
Borodai confirmed that his forces had recently refurbished what he described as a Strela-10, an old Soviet-era mobile surface-to-air missile system, which he said was a war trophy taken from the Ukrainian military. He said the weapon did not have enough power or range to shoot down a passenger jet at cruising altitude.
