Iran's military threatened on Tuesday to respond to Israel after strikes in southern Lebanon killed four people despite a deal between Tehran and Washington ending the Middle East war, including in Lebanon.

"If the child-killing army of the Zionist regime does not put an end to its acts of aggression in southern Lebanon, it should await a harsh response from the powerful armed forces of the Islamic Republic of Iran," said the Iranian military's central command Khatam al-Anbiya.

Israeli forces on Wednesday carried out airstrikes on several areas in south Lebanon, state media reported, despite a peace deal in the Middle East war that includes Lebanon.

The leaders of Canada, France, Germany, Italy, Japan, UK and the U.S. have called for an immediate ceasefire in Lebanon and for the disarmament of Hezbollah.

"In Lebanon, we support, through an immediate robust ceasefire, the Lebanese leadership's efforts to achieve the disarmament of Hezbollah and the monopoly of arms, and to protect Lebanon's territorial integrity and sovereignty with the appropriate international security guarantees," the G7 leaders said in a joint statement as they met in Évian, France.

Lebanon said Israeli strikes killed four people in the country's south on Tuesday as Israel said it intercepted Hezbollah rockets and launched raids, despite a U.S.-Iran deal that includes Lebanon.

An Israeli drone strike targeted a van on the Harees-Hadatha road in the Bint Jbeil district on Tuesday, as Israeli artillery shelling hit the vicinity of al-Rihan in the Jezzine district and the town of Kfartebnit in the Nabatieh region.

U.N. Secretary-General Antonio Guterres has called on Hezbollah to allow Lebanon’s government “to have the primacy of arms and authority throughout its territory,” U.N. spokesman Stephane Dujarric said.

Guterres also called on Israel to respect Lebanon’s sovereignty and territorial integrity and withdraw its troops.
