US secretary of state Marco Rubio said in an interview released on Wednesday that Iran must give up all nuclear enrichment if it wants to make a deal during talks with the Trump administration and head off the threat of armed conflict.

Iran insists its nuclear programme is for civilian energy use and says it does not seek to make weapons-grade uranium to build atomic bombs.
