Iran's state TV is reporting that the country's Supreme Leader Ayatollah Ali Khamenei has met with visiting Japanese Prime Minister Shinzo Abe amid tension between Iran and United States.
The meeting on Thursday morning, the second and final day of Abe's landmark visit, came amid reports of an oil tanker explosion in the Gulf of Oman.
Abe is the first sitting Japanese prime minister to visit Tehran since Iran's 1979 Islamic Revolution. On Wednesday, he warned that an "accidental conflict" amid heightened tensions between Iran and the U.S. must be avoided at all costs.
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.
