ISIS lost nearly half of its militants, land since 2014: US
Ground assaults and airstrikes have decreased the Islamic State's estimated size by nearly 50% after they lost 50,000 fighters since 2014, according to the Pentagon. After Libyan forces recaptured Sirte, ISIS' last stronghold in the country, the group lost half the land they controlled in 2014. Notably, an offensive is underway to retake the group's last Iraqi stronghold Mosul.
