An extremist opposition group killed a Syrian teenager on Sunday in front of his family in the city of Aleppo.

Graphic images of 15 year-old Mohammad Kattaa, a coffee seller in the war torncity, appeared on the internet yesterday. They appeared to show that the boy had been shot in the mouth and through the neck.

Reports said that the teenager was found arguing with another boy on Saturday.One report suggested that the other boy had attempted to get a free coffee, leading to Kattaa to say that, “even if Prophet Mohammad (pbuh) comes down, I will not give it as debt.”

He was later said to have been detained by an extremist group in the area, beaten and then shot when his mother and father had been found so that they could be forced to witness the execution.

“An unidentified Islamist rebel group shot dead a 15-year-old child who worked as a coffee seller in Aleppo, after they accused him of blasphemy,” said the London-based opposition Syrian Observatory for Human Rights director Rami Abdel Rahman.

“They spoke classical Arabic, not Syrian dialect. They shot the boy twice, once in the mouth, another in his neck, in front of his mother, his father and his siblings,” he said.

Later reports suggested that the group that is said to have carried out the killing had links to a number of al-Qaeda groups fighting the Syrian government.
