US President Donald Trump said on Friday that he has not decided whether to launch major strikes on Iran, as Tehran is now getting 'very serious' in ongoing talks with Washington. Speaking to reporters in the Oval Office, Trump responded 'No, I haven't' when asked if he had made a decision on a large-scale military operation. He added that discussions are continuing and that Iran appears to be 'getting more and more serious as the days go by, for maybe the obvious reason.' The remarks follow reports that Trump had been meeting with advisors to weigh options for a potential strike. The US and Iran have been engaged in talks, though tensions remain high. No further details on the negotiations or military plans were provided.
