The Iranian Revolutionary Guard Corps (IRGC) has said it will deliver a "regret-inducing response" if strikes against Lebanon are not ended immediately, state broadcaster Islamic Republic of Iran Broadcasting (IRIB) reports.
In a message on Telegram, the outlet says: "We have a stern warning to the oath-breaking United States and its Zionist partner in slaughter.
"If the aggressions against dear Lebanon are not brought to an immediate end we shall fulfil our duty and deliver a regret-inducing response to the malicious aggressors in the region."
State-run Islamic Republic News Agency (IRNA) quotes an IRGC official as saying: "Any attack on the proud Hezbollah is an attack on Iran. The [military] field is preparing a heavy response to the regime’s [Israel’s] savage crimes."
