Answer: They died, but no body was shown.
Explanation:
Did Bruno die? In the end to The Boy In the Striped Pajamas, both Bruno and Shmuel enter into a gas chamber in the concentration camp and are killed. This happens shortly after Bruno joins Shmuel in the camp, and the moment before the boys are gassed, Bruno tells Shmuel that he is his best friend. The film ends by showing the closed door of the now silent gas chamber, indicating that all prisoners, including Bruno and Shmuel, are dead.
