A Pakistani boy says he's sorry for taking part in a suicide mission.
The April 3 attack on a Sufi shrine in Dera Ghazi Khan in central Pakistan left more than 40 people dead.
The boy was arrested after his belt of explosives failed to go off.
In a television interview from his hospital bed, the boy said he is "seeking forgiveness" from the families of those killed and wounded.
He said he had been trained by militants close to the Afghan border, and that his handlers spoke of "more than 350 other boys going through the training."
The boy, who police estimate is 14, said he spent two months training with four other boys in the town of Mir Ali in North Waziristan, a region that is under militant control.
The Pakistan army has yet to launch an offensive there despite U.S. pressure, saying it does not have the resources.
The boy gave his name as Omar, though police had first identified him as Fida Hussain.
