On April 28, the US-backed Syrian Democratic Forces (SDF) redeployed many of its units from the Omar oil fields in the southeastern Deir Ezzor countryside to its positions around the ISIS-held town of Hajin, according to a report by the Syrian Observatory for Human Rights (SOHR).
The SOHR said that the redeployment of these units is a part of the ongoing preparations of the SDF and the US-led coalition for launching a joint military operation against the remaining positions of ISIS on the eastern bank of the Euphrates River.
Local observers believe that more than 1,000 fighters and commanders of ISIS are currently stationed in Hajin and several other villages along the eastern bank of the Euphrates. Previous battles around Hajin have shown that these besieged fighters are well-armed and willing to fight.
During the last few weeks, several US officials, including US Secretary of Defense James N. Mattis, have said that the US-led coalition and its Syrian allies are preparing to resume their campaign against ISIS in eastern Syria.
The Kurdish-dominated SDF has not conducted active operations against ISIS since the beginning of the Turkish attack on the Afrin area on January 20. According to experts, this has allowed the terrorist organization to reorganize its forces in eastern Syria, which will make any new operation more complicated.
