War on women.

BEIRUT, Jan 14 (Reuters) – Al Qaeda’s Syria wing, Nusra Front, shot dead a woman in the northwest of the country after accusing her of adultery, a monitoring group said on Wednesday, saying it showed such execution-style killings were not confined to the militant Islamic State group.

Islamic State, which split from al Qaeda and has seized land in Iraq and Syria, has beheaded and stoned to death Syrian and foreign civilians and combatants for crimes it sees as violating its strict interpretation of Islamic law.

But Nusra Front, which sometimes fights alongside Western-backed insurgents in Syria as well as against them, has also carried out such killings or physical punishments after accusing people of violations such as insulting God or thievery.

Both groups have been targeted by U.S.-led strikes which started last year.

Rami Abdulrahman, director of the Britain-based Syrian Observatory for Human Rights, said he received a video showing the woman being shot in the head outside Idlib city after being charged with adultery. Before she was killed, she begged to see her children but her killer refused, he added.

Photos posted on Twitter said to be of the woman showed her dressed in a black robe, headscarf and a red jacket and crouching on a pavement next to a group of standing men who appeared to be from Nusra Front. One man clothed in black wore a balaclava and held an assault rifle.
