The militia alliance that controls much of north-eastern Syria will merge with new state institutions, the presidency says.

The Kurdish-led and U.S.-backed Syrian Democratic Forces (SDF), which controls much of Syria's oil-rich northeast, has signed a deal agreeing to integrate into Syria's new state institutions, the Syrian presidency said on Monday.

US forces in eastern Syria continue to work closely with the Syrian Democratic Forces (SDF) and the Syrian Free Army (SFA). However, the agreement between SDF commander Mazloum Abdi and Syrian President Ahmad al Sharaa to integrate eastern Syria into the country’s new governing institutions could affect the US role in Syria and the broader anti-Islamic State campaign.
