US-backed Syrian fighters seize parts of IS 'capital' Raqqa
A U.S.-backed Syrian opposition force said on June 11 that it had captured a northwestern neighborhood of the Islamic State of Iraq and the Levant (ISIL) self-declared capital of Raqqa, making it the second district to fall into their hands in as many days after the group launched a wide offensive to gain control of the extremists' de facto capital.
