'Our hands are on the trigger' - Iran warns it knows where Israel's nuclear sites are

Iran's nuclear programme exists for peaceful purposes the country has always insisted.

But its military has warned that stance may change if Israel targets its nuclear infrastructure.

"The threats of the Zionist regime against Iran's nuclear facilities make it possible to review our nuclear doctrine and deviate from our previous considerations," said Ahmad Haghtalab, a senior Iranian Revolutionary Guards commander who is in charge of nuclear security.

Meanwhile, the UK and US have sanctioned Iranian firms involved in drone and missile production.
