According to the Syrian Observatory for Human Rights, the Syrian military's attack against the Syrian Democratic Forces (SDF) headquarters killed 21 and injured 125, prompting a response from American assets in the region.
"International coalition forces are bombing popular forces fighting "Daesh" and the SDF [Syrian Democratic Forces] east of the Euphrates river and there are reports of casualties", the statements said.
US-led coalition has killed more than 100 troops allied with the Syrian regime in an overnight operation carried out in retaliation for an attack on Kurdish forces.
The US-led coalition had observed a slow build-up of pro-government forces in the area over the past week and had alerted Russian Federation, which backs the Syrian government, to the presence of SDF forces in the area, according to the official.
Nebenzia said it was also "regrettable" that the Security Council wouldn't support a statement that Russian Federation sought Wednesday following an attack in Damascus that damaged its trade mission. A year later, Russian Federation joined the fighting in support of Syrian President Bashar al-Assad's government. Russian Federation said it did not have personnel in the area, and its defense ministry said it only confirmed 25 Syrian militia were wounded, and no deaths.
The U.S. official claimed that the pro-Assad forces were "likely seeking to seize oil fields in Khusham that had been a major source of revenue for Daesh from 2014 to 2017".More news: Man charged in DUI crash that killed Colts player Edwin Jackson
"Assad's regime is corrupt, and his methods of governance and economic development have increasingly excluded certain ethnic and religious groups", Tillerson added.
Russian, Turkish, and Iranian leaders reportedly planned to meet to discuss Syrian peace efforts.
"You've all seen how we reacted to that", Mattis said, referring to last year's cruise missile strikes. The U.S. has long supported the Syrian Democratic Forces, often characterizing the group as "moderate", and crediting them for playing a significant role in the defeat of ISIS in Syria.
This is a line that the coalition and the Syrian regime has agreed to and which their forces are not supposed to cross so as to prevent any conflicts.
We review the key events in Syria, including Damascus accusing Washington of a war crime after a coalition airstrike reportedly killed scores of pro-government fighters, more than 70 people killed in Eastern Ghouta and Turkey resuming airstrikes on Afrin after a brief lull.
Russia's foreign ministry meanwhile claimed Thursday that the USA airstrike on pro-Assad troops reflected Washington's attempts to seize Syrian economic assets. In June, the coalition shot down a Syrian warplane near Raqqa, accusing it of getting too close to its local ground forces.
