The U.S. Navy says it’s investigating whether two members of its elite SEAL Team Six were responsible for killing a Green Beret at the U.S. Embassy in Mali last June. Army Staff Sgt. Logan Melgar was found strangled to death in his room at the embassy in the capital, Bamako, where he was assigned to train Malian forces in counterinsurgency. The investigation of Melgar’s death comes as the Trump administration expands the role of AFRICOM across the African continent.
