A top Iranian diplomat expressed disappointment on Sunday after meeting a British Foreign Office minister amid escalating regional tensions, saying their talks were "repetitive", state news agency IRNA reported. Minister of State for the Middle East Andrew Murrison had the "usual talking points", said Kamal Kharazi, the head of the Strategic Council of Foreign Relations at Iran's foreign ministry. The JCPOA is the Joint Comprehensive Plan of Action, a multilateral 2015 nuclear deal that the US unilaterally withdrew from in May last year.
