The Iranian delegation arrives at the Coburg Palace in Vienna, Austria, where the 8th round of nuclear negotiations will resumes. The negotiations, attended by Britain, China, France, Germany, Iran, Russia and indirectly the United States, were halted at the end of last month. The resumption of talks comes after parties in recent weeks cited progress in seeking to revive the 2015 accord that was supposed to prevent Iran from acquiring an atomic bomb, a goal it has always denied pursuing.
