akubiyah was a mostly Christian village principally comprised of Armenian Orthodox and Catholic churches which after being taken over by the FSA was subsequently held by ISIS. The local Christians saw no distinction between the invading FSA and ISIS fighters as it was primarily the US-backed FSA which began massacring Christians and looting churches.
Even the US government funded Voice of America news had this to say based on an interview with a Christian survivor:
Christian refugees described to VOA the execution of a half dozen of their co-religionists in the northwestern village of al-Yakubiye, in Idlib province, by Sunni Muslims aligned with the Western-backed Free Syrian Army. Rahel, a 45-year-old former teacher, said, “Al Nusra didn’t come to our village; the people who came were from villages close by, and they were Free Syrian Army.”
...Nearly a third of Syria’s Christians, an estimated 600,000, have fled the country. Before the war, Christians accounted for about 10 percent of Syria’s population of 22 million.
And The Daily Beast also confirmed at the time that "nearly all Christians have fled [Yakubiyah] after half a dozen were executed with their heads chopped off and about 20 more were kidnapped" by the US sponsored FSA.
Furthermore, an October 2013 report in Arabic media confirmed that,
Terrorists belonging to al-Nusra front broke into homes in Yakubiyah in Syria's Idlib province, killed a Chrisitan man and destroyed a Virgin Mary statue. Upon arrival at a house that had the statue of virgin Mary, Wahhabi cleric, Omar Gharba' carried the statue of the Virgin Mary after it was taken over by militants from the "Islamic State in Iraq and the Levant" (ISIL) and broke it by throwing it on the ground. He stated that he and his fellow Wahhabis won't tolerate any form of worship except strict Wahhabism of Saudi Arabia.
"God willing, Only God will be worshipped in the land of the Levant," the terrorist who destroyed the statue said, noting that "no other idol will be worshiped after these days . We won't accept but the religion of Allah and the Sunnah of our Prophet Mohammed bin Abdullah."
In 2012 and 2013 Omar Gharba's name appeared somewhat frequently in Western news reports as he was interviewed on a few occasions and presented as a "moderate" rebel, for example by BBC Arabic in 2012.
The below video is one such example of Omar Gharba insisting that he and his fellow FSA militants would be tolerant and respectful of Christians and other religious minorities should they inherit power by toppling the Assad government - though he was subsequently outed as the destroyer of the Virgin Mary statue, as the edit of the video interview makes clear.
