Israel has carried out at least four air strikes on the historic Lebanese port city of Tyre, hours after expanding its evacuation orders to cover several central neighbourhoods, Lebanon’s state news agency says.

Lebanon state media reported 17 Israeli raids on Beirut's southern suburbs, with six buildings levelled and the vacated offices of a pro-Iran broadcaster hit on Wednesday, as the Iran-Hezbollah war reached its one-month mark.

AFP correspondents reported several strikes on Lebanon's Tyre on Wednesday after the Israeli army warned residents to evacuate swathes of the coastal city which boasts a UNESCO world heritage site.Residents began to flee immediately after the Israeli army called on residents of large parts of Tyre to leave ahead of military operations targeting Lebanese militant group Hezbollah.
