International Atomic Energy Agency officials are expected to press Iran for access to its Parchin military site, where officials suspect Iran has built a container for explosives tests. Western diplomats say they suspect Iran is buying time to remove any incriminating evidence before they allow U.N. inspectors inside the facility. Herman Nackaerts is the head of the IAEA delegation.伊朗当局和联合国核机构官员在维也纳展开洽谈。国际原子能组织官员预计将会敦促伊朗开放帕尔钦军事基地;他们怀疑伊朗在此修建了一个用于核高爆试验的容器。西方外交官称伊朗正在拖延时间,以便在联合国核查人员获准进入该设施前,转移任何控诉证据。赫尔曼·纳克茨是国际原子能机构代表团的负责人。
