A Turkish drone targeted an SDF military site on Thursday in the village of Mashirfa Al-Hammah on the Hassakeh - Tal Tamr road resulting in several casualties, Al Mayadeen's correspondent to northeast Syria reported.

Later, sources to Al Mayadeen indicated that another SDF military site was targeted by a Turkish drone in the same area resulting in significant material damage to the site which served as an important SDF military facility. Furthermore, it was reported that two Turkish drones targeted SDF sites in Tel Habbash and Sdad Al-Jawadiyah in al-Hasakah.

The sources also mentioned that the SDF evacuated its positions and headquarters inside the Al-Omar oil field in the countryside of Deir Ezzor, eastern Syria.

Earlier this week, Ankara was rocked by a two-part terrorist attack (a suicide bombing and shooting operation) just hours before the parliament was scheduled to reopen after a summer recess.

One of the terrorists detonated himself and then gunfire ensued with the other two, injuring two police officers.

Yesterday, sources to Al Mayadeen revealed that a Turkish drone targetted a military vehicle belonging to the SDF in the neighborhood of Gweiran in al-Hasakah in the far north-east corner of Syria.
