A Palestinian teenager says that Israeli soldiers detained him for five days last month, forcing him to sleep blindfolded and handcuffed in his underwear and to search and dig for tunnels in Khuza’a, his village near Gaza’s eastern border, which was all but destroyed in the fighting.

The teenager, Ahmed Jamal Abu Raida, said the soldiers assumed he was connected to Hamas, the militant Islamist group that dominates Gaza, insulted him and Allah and threatened to sic a dog on him.

“My life was in danger,” Ahmed, 17, said in one of two lengthy interviews on Thursday and Friday. As soldiers made him walk in front of them through the neighborhood and check houses for tunnels, he added, “In every second, I was going to the unknown.”

His assertions, of actions that would violate both international law and a 2005 Israeli Supreme Court ruling, could not be independently corroborated; Ahmed’s father, Jamal Abu Raida, who held a senior position in Gaza’s Tourism Ministry under the Hamas-controlled government, said the family forgot to take photographs documenting any abuse in its happiness over the youth’s return, and disposed of the clothing he was given upon his release.
