The U.S. military is dropping "cyber bombs" on ISIS for the first time as part of a stepped-up coordinated effort that has put increasing pressure on the militant group, Deputy Defense Secretary Robert Work said on Tuesday.
"Those guys are under enormous pressure. Every time we have gone after one of their defended positions over the last six months, we have defeated them. They have left, they have retreated," Work told reporters on a military plane en route to a Colorado air base.
He said U.S. and coalition forces were putting pressure on ISIS from all directions, using every possible military capability, including cyber attacks, to defeat the group.
