Syria's military command said on Sunday it had taken full control of the city of Palmyra. In a statement, the Assad government said the victory marked the beginning of the collapse of the Islamic State group. At the same time, the Wall Street Journal has reported that rift is growing between Islamic State's foreign and local fighters with recent battlefield setbacks in Iraq and Syria exacerbating latent strains within the terror group as it contends with financial hardships and territory loss. Foreign fighters, long welcomed by Islamic State as essential parts of its global mission, are generating greater internal discord and even violence just as the group pivots outward to target Europe and the US, the Wall Street Journal reported, the Journal said in a report. "With time, and because of the financial and management differences between them, the locals started to complain" about the foreign fighters, a Mosul resident was quoted as saying. "We all hope to see the day when this division among the fighters ends them." "Throughout Islamic State-controlled territory in Iraq and Syria, tempers are flaring, showing how recent battlefield setbacks in Iraq and Syria can exacerbate latent strains within the group as it contends with financial hardships and loss of territory," the report said.
