Irans parliament has passed a bill to approve the historic nuclear agreement agreed with world powers in July, paving way for its official implementation.
The bill to approve the Joint Comprehensive Plan of Action (JCPOA) agreed in Vienna on 14 July received the support of 161 lawmakers, with 59 voting against and 13 abstentions.
The agreement was earlier approved by the US Congress after President Barack Obama received support from enough senators to stop an attempt by the opposition to stop the process.
Iran is expected to start reducing its nuclear activities on 18 October to meet the requirements of the International Atomic Energy Agency (IAEA). The day is referred to as Adoption Day in the timeline towards sanctions relief.
The IAEA has a deadline of 15 December to report its findings to the United Nations before the process moves toward Implementation Day, when nuclear-related sanction against Iran will be dropped.
