Flights between Iran and Azerbaijan and Armenia have resumed following a ceasefire in the Nagorno-Karabakh region, the semi-official ISNA news agency reported on Wednesday, citing the spokesperson of Iran's civil aviation organization.
Iran had earlier cancelled all flights to Azerbaijan and Armenia until further notice for security reasons.
On Tuesday, Azerbaijan launched a military operation in the region of Nagorno-Karabakh, demanding the Armenian forces withdraw from the territory.
