Around half of the rebel fighters in Syria are foreign Islamists who aren’t interested in toppling the Assad regime. Instead, they’re seeking to implement Sharia law throughout the country, according to a prominent French doctor. ­The co-founder of the medical charity Doctors Without Borders, Jacques Beres, discovered some interesting information while treating Syrian rebels in the besieged city of Aleppo.According to Beres, 60 per cent of his patients during his two week service in Syria were rebels– and about half of those were foreign. He says the fighters aren’t focused on the fall of the Assad regime. Instead, they have their eyes on a different kind of prize – implementing Sharia law throughout the country."It's really something strange to see. They are directly saying that they aren't interested in Bashar Assad's fall, but are thinking about how to take power afterward and set up an Islamic state with Sharia law to become part of the world Emirate," the French doctor told Reuters.The foreign jihadists include Frenchmen who believe they are waging a “holy war,” claiming they’re inspired by Mohammed Merah, an Islamist militant from the French city of Toulouse. Merah killed seven people in March, in the name of Al-Qaeda.
