Iranian state media reported on Thursday that Araqchi made the remarks after an exchange with the Emirati delegation at the BRICS gathering, where divisions over the Iran war threatened efforts to issue a joint communique.

“I didn’t name the UAE in my statement for the sake of unity,” Araqchi was quoted as saying. “But the truth is that the UAE was directly involved in the aggression against my country.”

Iranian media did not specify the comments made by the Emirati representative that prompted the response.

The diplomatic dispute followed the UAE’s denial this week of claims by Israeli Prime Minister Benjamin Netanyahu that he had visited the Gulf state during the ongoing Iran conflict.

Araqchi had earlier warned that countries “colluding with Israel to sow division will be held to account,” remarks widely interpreted by regional analysts as directed toward Gulf states accused by Tehran of covert coordination with Israel and the United States.

The Iran war began on Feb. 28 with U.S. and Israeli strikes targeting Iranian facilities, prompting retaliatory missile and drone attacks by Tehran against U.S. bases and other targets across Gulf countries.

Iranian officials have increasingly accused regional governments of facilitating military operations against the Islamic republic, particularly states hosting U.S. military installations.

According to Iranian state media, Araqchi argued during the BRICS meeting that reliance on U.S. military bases and security cooperation with Israel would not guarantee the UAE’s stability.

“We must live side by side in peace, and this requires peaceful relations and complete understanding between the two countries,” he said.

The Wall Street Journal reported earlier this week that the UAE conducted military operations against Iran in early April. Reuters could not independently verify the report. Western and Iranian officials have also said Saudi Arabia carried out multiple unpublicized strikes against Iranian targets during the conflict.

The growing friction between Tehran and Abu Dhabi has complicated diplomatic dynamics within BRICS, the bloc comprising Brazil, Russia, India, China, South Africa and several recently admitted members, including Iran and the UAE.

Iranian media cited Deputy Foreign Minister Kazem Gharibabadi as saying there were “problems and communications” within the summit process because of the UAE’s participation.

The meeting in New Delhi was expected to focus on geopolitical coordination, trade cooperation and reform of global institutions, but the Iran war increasingly overshadowed proceedings as member states struggled to reconcile competing regional interests.
