Islamic State (Isis) militants in Syria have reportedly issued a circular banning residents of Raqqa from holding public gathering for Eid al-Fitr celebrations over fears that the Assad forces are planning to launch an air attack on the city on the day of Eid.
Syrian underground media activist group - Raqqa is Being Slaughters Silently (RBSS) - has reported on its social media accounts that people have been asked to avoid public celebrations during Eid al-Fitr.
Isis also reportedly has placed concrete blocks filled with oil across the city and residents have been asked to light them up during an air raid.
Recently, Isis had issued a similar ban, asking rseidents of Mosul to avoid Eid al-Fitr celebrations and prayers on the ground that such customs were not part of 'early Islam' during Prophet Mohammed's time.
In recent months, Raqqa, which is the de facto capital of the Islamist radical group, has faced heavy casualties.
In June, the Kurdish militia, YPG, assisted by US-led coalition airstrikes, killed many Isis militants near Raqqa and captured several border towns from the group.
The U.S. Central Command on Thursday issued a statement that it conducted 15 air raids near five Syrian cities, including five near Raqqa and four near Hasaka, on 15 July.
