Flights from all Iran's airports will be canceled until 6 a.m. local time (0230 GMT) on Monday from 9 p.m. on Sunday, Iran's state media said, citing a spokesperson for Iran's Civil Aviation Organization.
The flights have been canceled due to operational restrictions, state media cited the spokesperson as saying without providing further details.
Iran implemented restrictions on flights on Tuesday when it launched missiles at Israel, in an attack to which Israel vowed to respond.
