On Friday, the US Department of Defense spokesperson Jeff Davis said senior leaders of the Daesh are leaving the Syrian city of Raqqa and moving operations to Deir ez-Zor and Madan.
The coalition carried out 14 additional strikes in Syria on Tuesday, engaging seven Daesh tactical units and destroying fighting positions, bridges and vehicles near Raqqa and Palmyra.
The strikes engaged Daesh tactical units, vehicles, weapons caches, command and control nodes, while also suppressing 13 mortar teams, among other targets.
The US-led coalition of 68 nations is conducting airstrikes against the Daesh in Syria and Iraq. The strikes Iraq are conducted in support of the Iraqi government, but those in Syria are not authorized by the government of President Bashar Assad or the UN Security Council.
