US military says using cyber capabilities against Islamic State

Proactive effort: Work (on the right) says the Islamic State is under enormous pressure

COLORADO: The US military is dropping "cyber bombs" on Islamic State 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.

"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.
