/VCGThe United Nations Security Council (UNSC) will vote on Friday on reimposing deep economic sanctions on Iran, which Tehran has described as "cruel," over its nuclear program. Britain, France and Germany, signatories to the Joint Comprehensive Plan of Action (JCPOA), allege that Iran has broken its promises under that 2015 treaty. Western countries and Israel have long accused Tehran of seeking to acquire nuclear weapons, a claim Iran denies. Under the JCPOA, Tehran agreed to curb its nuclear program in exchange for sanctions relief. The United States unilaterally withdrew from the deal in 2018, reimposed sanctions, and Iran subsequently reduced its compliance.
