Syria condemned what it called a “flagrant attack” that would have “dangerous repercussions”. In a separate incident, Iran’s Revolutionary Guards said they had launched several missiles from Iran into eastern Syria on Sunday, targeting IS fighters.The SU-22 incident took place on Sunday afternoon near the town of Tabqa, where the Syrian Democratic Forces (SDF) have been fighting Islamic State militants as part of a drive to retake the city of Raqqa, the IS stronghold further to the east. It is believed to be the first air-to-air kill of a manned aircraft by a US military jet since the Kosovo campaign in 1999.
