Washington (CNN) – The threat of ISIS is continuing to grow in certain areas despite the setbacks from U.S. led airstrikes a top intelligence official said Tuesday.

In testimony before the House Armed Services Committee, Lt. Gen. Vincent Stewart, Director of the Defense Intelligence Agency, said the group has been able to extend its reach beyond its bases in Iraq and Syria.

“With affiliates in Algeria, Egypt, Libya, the group is beginning to assemble a growing international footprint that includes ungoverned and under governed areas,” Stewart said in prepared testimony to discuss various threats emanating from around the world.

Stewart also said the numbers of foreign fighters flowing in and out of Iraq and Syria is “troubling,” as the United States expects ISIS to continue its outreach to members of the global extremist movement as a way to boost its numbers.

As the United States works to train and help build the capacity of the Iraqi security forces to eventually dislodge ISIS from Iraq, Stewart warned the Iraqis still have a long way to go.
