Iranian foreign minister Abbas Araghchi has warned that his country would be forced to strike back at US interests in the Middle East in response to any renewed attack. "If the US attacks us, then we have every right to defend ourselves. If the US attacks us, that is the act of aggression. What we do in response is an act of self-defence," Araghchi said in an interview. The remarks comes ahead of the third round of talks between the two nations in Switzerland's Geneva.
