The vicinity of the Syrian city of Raqqah has been flooded with watter from the Tabqah dam recently captured by the US-backed Syrian Democratic Forces.
According to the SDF Press Center, ISIS terrorists had used irrigation channels (linked with the dam) to do this. However, it is not clear what goal ISIS could pursue with this move.
In turn, ISIS reported that the SDF did this by itself in order to flood ISIS undergroud tunnels in the area.
In any case, the city is on the verge of the humanitarian crisis.
ISIS actively uses and builds a network of undeground tunels around and inside the city. The terrorist group is going to use this network during the battle for Raqqah.
