Venezuela summoned the ambassador of Iran, a longtime ally, to face protest over comments that were deemed “contemptuous and inappropriate,” the foreign ministry said in a statement, AFP reports.

“The ambassador of the Islamic Republic of Iran to Venezuela was summoned to the Venezuelan Foreign Ministry in order to be given a note of protest over the contemptuous and inappropriate remarks made against Venezuela’s institutions and authorities,” the statement shared via social media said.

Asked by AFP, Venezuelan authorities did not specify what remarks they referred to, but video circulating online indicates Iranian Foreign Minister Abbas Araghchi had recently said Iran is “not Venezuela” when it come to negotiations with the United States.
