The United Arab Emirates Ministry of Foreign Affairs announced on Sunday that it is closing its embassy in Tehran and withdrawing its ambassador to Iran.

The Ministry of Foreign Affairs also said in the same statement that it is withdrawing all members of its diplomatic mission in Iran.

The decision was made "in response to the blatant Iranian missile attacks that targeted the UAE's territory," the statement reads, in part.

"These hostile attacks against civilian sites, including residential areas, airports, ports, and service facilities, endangered innocent civilians in a serious and irresponsible escalation and constitute a flagrant violation of national sovereignty, as well as a clear breach of international law and the Charter of the United Nations," the statement further said.

Iran's foreign minister, Abbas Araghchi, told his Omani counterpart on Sunday that Tehran welcomes "any serious efforts contributing to de-escalation and the restoration of stability," according to a social media post from the Oman News Agency.

The post said Omani Foreign Minister Badr bin Hamad Al Busaidii, who had been mediating the negotiations between the United States and Iran leading up to Saturday's joint U.S.-Israel military operation, spoke with Araghchi by phone.

Araghchi "conveyed the position of the Islamic Republic of Iran, which calls for peace, noting that the Israeli-US attack upon his country had exacerbated tension and alarm throughout the region, while affirming the Iranian side's openness to any serious efforts contributing to de-escalation and the restoration of stability," the post read.

The post further said al-Busaidii "affirms the Sultanate of Oman's continued advocacy for a ceasefire and a return to dialogue and negotiation to resolve the ongoing conflict through diplomatic means."
