Iran’s foreign ministry has rejected reports of the country’s willingness to “compromise” its stance in ongoing indirect negotiations with the United States to restore its 2015 nuclear deal with world powers.

Foreign ministry spokesman Saeed Khatibzadeh said late Saturday that Iran’s supreme leader, Ayatollah Ali Khamenei, made no mention of compromise to Qatar’s emir, Sheikh Tamim bin Hamad Al Thani, when they met in Tehran earlier this month.
