The missile strikes, which took place on Saturday, are a major escalation in Iran’s role in Syria. This is the first time Iran has fired missiles into Syria since the Arab country descended into a civil war in 2011.
The strikes come as ISIS claimed responsibility for two June 7th attacks in Tehran that targeted Iran’s Parliament building and a shrine dedicated to the republic’s revolutionary founder Ayatollah Khomeini.
It was the first time that ISIS, which is fighting Iranian-backed militias in Syria, has claimed responsibility for an attack in Iran.
Iran’s military had vowed revenge for the attacks that killed 12 people.
