TEHRAN -- Iran has extended the suspension of all domestic and international flights until Thursday afternoon, the Ministry of Roads and Urban Development said on Wednesday, citing passenger safety concerns following a recent conflict with Israel.

The decision was made "in light of recent developments and to ensure the safety and security of passengers and flights," ministry spokesperson Majid Akhavan said in a statement published on the ministry's website.

Iran closed its airspace on June 13 after Israeli airstrikes targeted Tehran and other locations. The extension of the closure comes despite a US-brokered ceasefire that took effect early Tuesday.

Separately, Alaeddin Rafi'zadeh, head of Iran's Public Administration and Recruitment Organization, said government offices and state-run institutions would resume normal working hours from Saturday, according to the semi-official Fars news agency.
