LONDON: Gulf Arab countries have written to the UN secretary-general protesting against Iran’s “unacceptable claim” to have imposed new rules for ships passing through the Strait of Hormuz. The letter also condemned Iran’s attacks on countries in the region for making sovereign choices related to “their security and international partnerships,” Bahrain News Agency reported on Thursday. The letter was sent by Bahrain, Saudi Arabia, the UAE, Kuwait, and Qatar, as well as Jordan, to UN chief Antonio Guterres and China’s UN ambassador Fu Cong, who is currently the Security Council president.
