Battle for Raqqa
Further east, Russian raids hit Raqqa, the stronghold of Islamic State of Iraq and the Levant (ISIL, also known as ISIS), killing at least 24 civilians and wounding 70 people, said the Observatory.
The monitor said another six people were also killed but it had not yet confirmed how many of them were civilians or ISIL fighters.
Russia said the raids destroyed a “chemical weapons factory” on Raqqa’s outskirts as well as a weapons storage facility and ISIL training camp to the north and southeast.
Its defence ministry said ISIL suffered “significant material damages” in the strikes and that “a large number of fighters have been killed”.
