A Raqa-based activist,Mohammad Nour Matar still missing

 Crimes by the Islamic militia 'State of Iraq and al-Sham' has been increasing, amid an atmosphere of bewilderment among Syrians. 

Reports emerged on Thursday that a Raqa-based activist,Mohammad Nour Matar, who has documented the uprising against Assad since its early days has been missed after an explosion by ISIS.

The prominent young activist, Amer Matar, told Zaman Alwasl via SKYPE interview that the destiny of his brother still unknown.

'We found his burnt Camera but no body for Mohamed, we look for it in the hospitals and everywhere but no news,'' Matar said.

The Islamic State of Iraq and Syria was detained the media activist last month outside its base... after he stood alongside a woman who tried to stage a sit-in," Matar's brother Amer told AFP.

In the early days of the Syrian uprising, when opponents of the regime were desperate for assistance from any quarter, jihadist fighters were welcomed but a spate of abuses is fueling a backlash, AFP said.

 Weeks ago, "Out, out, out, the (Islamic) State (of Iraq and Syria) must get out," protesters shouted at a rally in the northern town of Manbij, referring to an Al-Qaeda front group.

  There are two main Al-Qaeda linked factions, both with Iraqi origins, according to Washington -- the Al-Nusra Front, which has operational independence, and the Islamic State of Iraq and Syria (ISIS), a front for Al-Qaeda in Iraq.

Numerous other smaller groups, many of them composed almost exclusively of foreign fighters, are also operating on the ground.

Unlike the mainstream rebel Free Syrian Army, which has received weapons from several Gulf Arab governments as well as promises of US arms, the jihadist groups rely on private donations.

But there are enough wealthy benefactors attracted to their fundamentalist vision to ensure a steady stream of weapons, as well as volunteer fighters from around the world, many of them seasoned in other conflicts.

That has helped them become a fighting force out of proportion to their numbers, and they have captured several population centres.

But their imposition of their extreme form of Islam has increasingly alienated civilians.

In Raqa, the only provincial capital in rebel hands, the Al-Nusra Front is accused of detaining dozens of men.
