**Iran Halts Flights Amid Rising Tensions with Israel**

Flights from all Iranian airports have been suspended from Sunday night to Monday morning, according to an announcement by Iran's Civil Aviation Organization, reported by state media. The decision, effective from 21:00 Sunday to 06:00 Monday local time, is attributed to operational restrictions. However, further details on the restrictions were not disclosed.

This suspension of flights comes in the wake of escalating tensions between Iran and Israel. Last week, Iran launched a significant missile strike against Israel, firing some 200 missiles in retaliation after the killing of key figures allied to Tehran. Among those killed were Hezbollah chief Hassan Nasrallah and IRGC top general Abbas Nilforoushan in an Israeli air raid on Beirut. Furthermore, the attack also responded to the killing of Hamas leader Ismail Haniyeh on July 31 in Tehran, a move widely attributed to Israel.

On Saturday, Iranian Foreign Minister Abbas Araghchi issued a stern warning, promising a "proportional and similar reaction from Iran, and even stronger" should Israel proceed with any attacks. Adding to the nation's defensive preparations, Oil Minister Mohsen Paknejad visited a critical oil site in the Gulf on Sunday, reflecting concerns over potential Israeli strikes targeting Iran's oil infrastructure.

The unprecedented cancellation of flights underscores the high level of alert within Iran as the standoff with Israel intensifies.
