The IS controls much of the countryside of Deir al-Zour province, except the city which is still under government control but besieged by the IS, and has repeatedly carried out attacks against government positions in the oil-rich province.
Russian aircraft frequently carry out airdrops of aid and food to the besieged people in that city.
