The supreme leader, Ayatollah Ali Khamenei, said that Iran will “move toward” a nuclear weapon if attacked by the U.S. or Israel, just a day after President Donald Trump threatened bombing.

President Donald Trump is considering indirect nuclear talks with Iran, according to a report by Axios, which cited two unnamed U.S. officials, while also preparing the ground for military strikes. The proposal for indirect talks comes from Iran.

Iran is considering its options in deterring President Trump amid his repeated threats of direct military engagement by possibly launching its own strike on a U.S. base in the Indian Ocean.
