ISIS fighters seen firing anti-aircraft weapons – but now the US is taking the fight to the militants in the shape of cyber warfare.

The US 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 enroute to a Colorado air base.

He said US and coalition forces were putting pressure on ISIS from all directions, using every possible military capability, including cyberattacks, to defeat the group.
