ABU DHABI — The United Arab Emirates on Sunday summoned Iran’s charge d’affaires in Abu Dhabi in response to a speech by Iranian President Hassan Rohani that the foreign ministry described as “unacceptable.” Rohani said in a speech on Saturday the UAE had made a “huge mistake” in reaching an agreement to normalize ties with Israel and called it a betrayal by the Gulf state. “They [the UAE] better be mindful. They have committed a huge mistake, a treacherous act,” he said of the agreement announced on Thursday. The UAE foreign ministry said the speech was “unacceptable, inflammatory, and carrying serious repercussions for the security and stability of the Arabian Gulf region,” a statement carried by state news agency WAM said. The charge d’affaires has been given a “strongly worded memo,” added WAM. The foreign ministry reminded Iran of its duty to protect the UAE diplomatic mission in Tehran. To protest the UAE-Israel agreement, a small group of Iranians gathered in front of the UAE embassy in Tehran late on Saturday, Iranian media reported. — Agencies
