- A Russian Su-25 fighter jet is shot down by a MANPAD while on a patrolling mission over the ″de-escalation zone″ in the Idlib governorate. The pilot, Roman Filipov, safely ejected via parachute but died on the ground in a brief exchange of fire with militants on the outskirts of Saraqib. HTS claimed responsibility for the downing. In response, the Russian Ministry of Defence released alleged footage of airstrikes on HTS territory in the area of the crash site.
- In response to the SAA offensive on the East Idlib front, 11 rebel groups announced the formation of a unified operations room, Dahar al-Ghaza ("Defeat the Invaders"), to counter the Syrian Army and allies' recent advances.

The US-led coalition conducted strikes against the pro-government forces in support of the SDF. According to one US official, more than 100 pro-government fighters were killed, while about 500 troops participated in the attack; no Americans were injured or killed during the engagement. At a news briefing, Pentagon spokeswoman Dana White claimed the US is "not looking for a conflict with the regime." According to a source close to the Syrian Army, approximately 25-30 Al-Baraka tribesmen were killed in the airstrikes. The Al-Baraka tribesmen are also from the Euphrates River Valley and considered locals. The Russian government later admitted several dozen of its citizens died or were injured during the engagement.
- UN High Commissioner for Human Rights Zeid Ra’ad Al Hussein called for international action after "one of the bloodiest periods of the entire conflict", mainly in Eastern Ghouta and Idlib.

- SDF fully seized Al-Bahrah town from ISIL along the Euphrates.
- Airstrikes and artillery attacks on the Eastern Ghouta suburbs of Damascus killed at least 46 people on Thursday, according to Agence France-Presse, bringing the six day death toll to over 400. The UN was unable to reach an agreement on a ceasefire resolution, due to Russian blocking.

- TFSA/TSK forces seized control of the Maydanki dam and its western bank in Afrin. The dam serves as a water supply to Afrin city.

The government flag was raised in Jayrud two days later as the last batch of rebels evacuated, signifying government control in the former rebel enclave.
