US President Donald Trump and the Syrian Democratic Forces (SDF) have announced that the village of Baghouz has been re-captured from the Islamic State (IS) group. It was the last enclave controlled by the group in Syria. In order to quash the jihadists, the SDF have relied on the international US-led coalition, which provided air support. French forces played a strategic role, notably thanks to their airbase in nearby Jordan. Our regional correspondent Antoine Mariotti met up with them.
