Iran has fired missiles at Israel for the first time in months, as Tehran's ceasefire with the US hangs by a thread.
The Israeli Defence Force (IDF) put out a statement on social media: "The IDF identified missiles launched from Iran toward Israel. Defensive systems are operating to intercept the threat."
Iran's Islamic Revolutionary Guard Corps (IRGC) said "this operation is not a passing event, but rather the beginning of a full week of continuous strikes".
In a statement it added: "Waves of missiles and drones will continue to be launched around the clock for the next seven days until the enemy is deterred and ceases its crimes.
"Any targeting of Iranian territory will be met with a devastating and overwhelming response beyond all expectation."
This comes as earlier today Israel hit southern Beirut in the first attack on the Lebanese capital since a truce brokered by the US last week.
Two air strikes on two apartment buildings in a stronghold of Iran-backed Hezbollah killed two people and injured at least 20, including women and children, Lebanon's health ministry said.
Ebrahim Rezaei, a top advisor to Iran's supreme leader, said Iran had repeatedly warned it would not tolerate ceasefire violations and attacks on Lebanon.
