In the most extensive and heaviest bombardment in weeks, Syrian and Russian warplanes pounded the rebel-held enclave in the Idlib-Hama-east Latakia region, deemed a "de-escalation zone" since the 2018 demilitarization agreement. Russia confirmed they, in coordination with Turkey, targeted Hayat Tahrir al-Sham drones and weapons stockpiles. Among dozens of rocket strikes, usage of incendiary and cluster munitions were reported as well.
