Jabhat al-Nusra declares nothing to do with death of Al Shaar boy

 a statement apparently from Jabhat al-Nusra about the killing of a 14-year-old boy, who parents say was killed by three armed men after he said he won't offer coffee to customers for money to be paid later:

"We Jabhat al Nusra confirm the following:
We have nothing to do with the issue involving the death of a boy in Al Shaar area for allegedly making a blasphemous comment (cursed the prophet peace be upon him).
2. Based on this, we condemn what happened and affirm that this type of behaviour is not part of sharia."
