The evil men had tortured the boy before choking him and hiding his body in an abandoned house,
reports in the Middle East claim.
Abdul Jalil al-Ashhab, 19, Mohammed Said al-‘Uqri, 27, and Ghaleb al-Rashdi, also 19, were all executed by a firing squad yesterday.
The young boy was abducted while heading to his grandmother’s house, then handcuffed and attacked in a nearby school.
His body was found four days later.
Yemen’s legal system allows people to be killed by shooting, hanging and beheading.
