According to CNN, anti-ISIS activists in Raqqa said the city seemed to be bracing for an attack even before the French air raid.
A member of the group reported that streets were empty before the airstrikes, with ISIS fighters appearing to have deserted many areas.
"They counted 30 bombs that also hit a stadium, a museum, and a medical facility, among other things, reports the Washington Post."
Water and electricity were cut off in the city due to the strikes, so-far no civilian casualties have been reported so far.
The French government launched a retaliatory assault on the ISIS de-facto capital in Syria just two days after the terrorist group claimed responsibility for the deadly Paris attacks that killed hundreds last Friday.
The Mirror reports that a raid on the ISIS stronghold of Raqqa was carried out on Sunday as part of Operation Chammal, a French military operation targeting ISIS.
According to the French Ministry of Defence, 10 fighter jets launched simultaneously from bases in the United Arab Emirates and Jordan and dropped 20 bombs on Raqqa between 7:50 p.m. and 8:25 p.m. French time.
A command center, terrorist recruitment center, ammunition storage base, and training camp were destroyed in the assault.
