A Turkey-based Syrian activist and her journalist daughter have been found dead from stab wounds at their apartment on the Asian side of Istanbul.
Turkey's state-run Anadolu news agency reports that the bodies of 60-year-old Arouba Barakat and her 22-year-old daughter, Hala Barakat, were discovered late on September 21 after friends alerted police that the journalist had not shown up for work earlier in the day.
Other Turkish media reports said Aurouba Barakat had been investigating alleged torture in prisons run by the Syrian government.
Syrian opposition activists say Arouba Barakat was a member of the Syrian National Council, an Istanbul-based moderate opposition group that was formed in August 2011 and opposes the government of Syrian President Bashar al-Assad.
Her daughter was a journalist working for the Syrian opposition's Orient news.
Syrian Kurdish nationalists have accused the Syrian National Council of being overly influenced by Turkey.
Western scholars have described it as a conduit for attracting foreign funds and weapons to distribute to Syria's factionalized opposition.
