Government forces control rural areas in the south and east of Raqa province, while Kurdish fighters control the rest.
The city of Raqqa was the center of the IS group’s brutal “caliphate” until they were ousted from power in 2017.
Last week, IS announced the death of its leader Abu al-Hussein al-Husseini al-Qurayshi, whom it said was killed in clashes in northwestern Syria.
In March 2019, IS lost its last territory in Syria to a Kurdish-led counteroffensive backed by a US-led coalition, but jihadist remnants continue to carry out deadly attacks from hideouts in the vast Syrian desert.
The targets include civilians as well as government troops and pro-Iranian and Kurdish-led fighters.
