By early 2014, the aid group confirmed that Ms. Akavi was being detained in a facility next to an oil installation outside Raqqa. She shared a cell with an American aid worker, Kayla Mueller, according to the aid group and others who were in the same jail. But three British and four American citizens, whose governments hew to a strict no-ransom policy, remained behind, along with Ms. Akavi. She described how for most of the day, Ms. Akavi lay on the floor of their cell, apparently too ill to sit up. The Red Cross was warned in communications with ISIS that Ms. Akavi was sick, Mr. Daccord said, but never learned what was wrong.
