BERLIN (AP) — A U.S. military hospital in Germany says Army Sgt. Bowe Bergdahl is in “stable condition and receiving treatment for conditions requiring hospitalization” after arriving from Afghanistan and five years of captivity.

The Landstuhl Regional Medical Center says Bergdahl’s treatment “includes attention to dietary and nutrition needs after almost five years in captivity” but declined to release further details about his medical condition due to patient privacy laws.

The hospital said in a statement Monday that “there is no pre-determined amount of time involved in the reintegration process” for the 28-year-old.
