Tribal figures linked to a US-backed alliance announced plans Monday for a council to run Syria's Deir Ezzor, as the alliance and regime troops battle jihadists in and around the city.
The Observatory said deadly US-led coalition raids in support of that operation hit the village of Al-Shahabat earlier Tuesday, killing 12 members of a single family including five children.
They come as the Syrian army prepares to push into the eastern IS-held part of Deir Ezzor city, according to the Observatory.
The operation seeks to "oust Daesh from the city and the province completely", the military source said.
"Russian and Syrian regime warplanes are striking IS positions in the city and its outskirts".
Backed by Russian air power, government troops have breached ISIL's siege, captured the strategic Jabal Thardah region, and expanded control to half of Deir Az Zor city.

He recalled that the city of Deir ez-Zor, which used to be besieged by terrorists for more than three years, was unblocked by Syrian troops under the command of General Hassan Suhel on September 5.
It remained unclear whether the Deir Ezzor Civil Council would coordinate with, or rival, government authorities already present in other parts of the city.
Abdel Rahman said they had advanced to six kilometers (four miles) from its eastern banks, at a point across the river from Deir Ezzor city.
The US-led Coalition told Rudaw English that as of Tuesday, SDF partner forces "have liberated approximately 42,000 square-kilometers in Syria" which is estimated to be "77 percent of the territory previously held by ISIS".
It made no mention of regime forces, who are now in control of about half of Deir Ezzor city, and did not say whether the civil council would coordinate with, or rival, government authorities.
