Iran's Supreme Leader Ayatollah Ali Khamenei says that Tehran "will in no way repeat" negotiations with the U.S. amid tension over its unraveling the nuclear deal with world powers.
Khamenei made the comment on Thursday, during a meeting with Japanese Prime Minister Shinzo Abe who traveled to Tehran as an interlocutor for President Donald Trump to ease tensions between Washington and Tehran.
But the comments by Khamenei could indicate that Abe's visit may not have succeeded.
Khamenei's official website quoted him as telling Abe: "I don't regard Trump as deserving any exchange of messages and have no response for him and will give no response."
Earlier, Khamenei was quoted as saying by Abe that Iran has no intention of making or using nuclear weapons.
"Supreme Leader Khamenei made a comment that the country will not and should not make, hold or use nuclear weapons, and that it has no such intentions," Abe told reporters in Tehran following his meeting with Khamenei.

Abe's comment was broadcast on Japanese public broadcaster NHK.
Abe traveled to Tehran on Wednesday to warn that an "accidental conflict" could be sparked amid heightened tensions between Iran and the U.S., a message that came hours after Yemen's Iranian-backed Houthi rebels attacked a Saudi airport, wounding 26 people.
Abe's trip is the highest-level effort yet to de-escalate the crisis as Tehran appears poised to break the 2015 nuclear deal it struck with world powers, an accord that the Trump administration pulled out of last year. It's also the first visit of a sitting Japanese premier in the 40 years since the Islamic Revolution.
