According to Mikrofonnews Agency (MHA), U.S. aircrafts targeted positions of forces loyal to Assad regime in Deir ez-zor in the east of Syria after the forces had attacked forces supported by the United States of America.
U.S. officials say nearly 100 loyal forces to Bashar al-Assad were killed in retaliatory attack which was carried out on Wednesday. No U.S. troops have been killed or injured during the attacks, which targeted a military base of PYD/PKK.
A U.S. official said around 500 troops loyal to Assad regime attacked the base, using mortar and tanks made by Russia. Forces supported by the United States of America said the attacks were very unexpected and were carried out without reason.
