The Pentagon said Friday that it is not currently equipped to detain Islamic State prisoners for long periods of time, just days after the soon-to-be leader of U.S. Central Command said that’s a capability the U.S. needs to have.

Col. Steve Warren, a spokesman for Operation Inherent Resolve, said Friday that the U.S. decides how it will handle Islamic State fighters captured on the battlefield on a “case-by-case” basis.
