The missile strikes are also being used to warn "some reactionary countries" of the sub-region, and Saudi Arabia was expressly singled out as one of them, with allegations that "they are trying to bring insecurity into Iran".

Clashes between Syrian troops and the SDF would escalate tensions and open a new front line in the many complex battlefields of the civil war, now in its seventh year.
The Iranian attack inside Syria came on the same day the United States shot down a Syrian fighter jet that was bombing US-backed Kurdish rebels in Raqqa.
"The launch of these missiles had previously been coordinated with Syria and the missiles entered the Syrian airspace through Iraq", he was quoted as saying.
