“A Jesuit missionary who was abducted in northeastern Syria in July has been killed, according to one of the country’s most prominent rebel activists. Lama al-Atassi, secretary general for the Syrian National Front, wrote on her Facebook page that Italian priest Paolo Dall’Oglio, 59, has been executed. “It’s with deep sorrow that I inform you that I was told by a reliable source that father Paolo has been executed. May God have mercy of his soul,” she wrote. The Italian foreign ministry said it has no intelligence to confirm the claim………..”

This is just one source, but she is apparently considered a “reliable” pro-rebel source. Apparently there are still “reliable” Syrian sources on Syria, on both sides.
