TEHRAN: Iran's Supreme Leader warned the United States and Israel on Thursday not to launch any military action against its nuclear sites, saying it would be met with “iron fists”, state television reported.

“Our enemies, particularly the Zionist regime (Israel), America and its allies, should know that any kind of threat and attack will be firmly responded.

Our nation, the Revolutionary Guards and army will answer attacks with strong slaps and iron fists,” Ayatollah Ali Khamenei said.
