Iranian President Hassan Rouhani condemned “flagrant US aggression on Syria” in a phone call with Syria’s Bashar al-Assad about Friday’s missile strikes on a Syrian air base, Tehran’s state-run Press TV said.

Rouhani called on Saturday for an impartial investigation of the suspected chemical weapons attack in Syria, which killed at least 70 people, and warned that US missile strikes in response risked escalating extremism in the region.
