A woman has been executed in Syria by her own son for asking him to leave the Islamic State (Isis) in the jihadist-controlled Syrian city of Raqqa, according to reports. Respected monitoring group Raqqa is Being Slaughtered Silently (RBSS) claimed 45-year-old Leena Al-Qasem was killed by her son Ali Saqr in a public execution for committing apostasy.

The anti-IS (Daesh) Syrian activist group also uploaded a photo of the man believed to be the son, and described him as a member of the terrorist group.

The group corrected the age of the woman to 45 after sending these tweets.

Activist group the Syrian Observatory for Human Rights also said their sources confirmed the woman was killed after "inciting her son to leave the Islamic State and escaping together to the outside of Al-Raqqah, and that the Coalition will kill all members of the organisation".

The claims arrive after RBSS said female journalists Ruqia Hassan was also killed by IS for writing about life in Raqqa since it became an IS-stronghold, as well as the documenting the coalition air strikes againt the group.

Hassan, who also went under the pseudonym Nisan Ibrahim, is believed to be the fifth journalist to be killed by IS since October 2015.

RBSS founder Abu Mohammed tweeted on 2 January what he claimed were Hassan's last words: "I'm in Raqqa and I received death threats and when Isis will arrest me and kill me it's OK because they will cut my head and I have dignity. It's better than I live in humiliation with Isis."
