(02.05.) Activists say rebels have clashed with Assad’s forces between Dumair air base, which they said came under heavy rocket fire from the rebels, and Sayqal air base about 40 km (25 miles) further east where the chemicals are believed to be held. (…)

Activists said the fighters are from the Islamic Front – one of the largest and most powerful Islamist rebel coalitions – the Rahman Corps and Ahmad Abdo Brigades. The offensive appeared to be funded by Gulf Arab supporters, they said.
