Iran's supreme leader Ayatollah Ali Khamenei said Wednesday that Israel's attacks during last month's 12-day war were intended to weaken the Islamic republic's system and spark unrest to topple it.

Hardline ideologues, who advocate for perennial enmity with the west, have railed against the possibility of re-engaging with the US and attacked Iran’s reformist president Masoud Pezeshkian, who this week suggested he remained amenable to negotiations with Washington.

Iran’s government has issued a new death toll for its war with Israel, saying at least 1,060 people were killed.
