An Islamic State commander described by the Pentagon as the group's "minister of war" was likely killed in a US air strike in Syria, US officials said on Tuesday, in what would be a major victory in the United States' efforts to strike the militant group's leadership.
Abu Omar al-Shishani, also known as Omar the Chechen, ranked among America's most wanted militants under a US program that offered up to $5 million for information to help remove him from the battlefield.
