Pakistani Prime Minister Imran Khan saidon Tuesday Donald Trump had asked him to mediate with Iran to defuse tensions, though the US president later suggested it was Khan who approached him and nothing was final.

Khan met Trump and Iranian President Hassan Rouhani on the sidelines of this week’s United Nations General Assembly, before which he visited Crown Prince Mohammed bin Salman in Saudi Arabia, whom he said had made the same request.

“Trump asked me that if we could de-escalate the situation and maybe come up with another deal,” Khan told reporters at the gathering of world leaders in New York.

“Yes, we did convey this, and yes, we’re trying our best,” he said.

“I immediately spoke to President Rouhani yesterday after the meeting with President Trump. I can’t say anything right now more than this, except that we’re trying and mediating,” he added.
