WASHINGTON -- The US military believes that some 50,000 Islamic State fighters have been killed since the United States started battling the group more than two years ago, a senior US military official said on Thursday, calling it a "conservative estimate."
The official, who spoke to Pentagon reporters on condition of anonymity, said the figure showed how the United States was effectively combating the group with US-led coalition airpower and limited US troop deployments in support of local forces.
