Question: How many members are there in the group that imposed sanctions against Iran because of their nuclear program?

full_context: Document 1: United Nations Security Council: The Security Council consists of fifteen members. The great powers that were the victors of World War II -- the Soviet Union (now represented by the Russian Federation), the United Kingdom, France, the Republic of China (now represented by the People's Republic of China), and the United States -- serve as the body's five permanent members. These permanent members can veto any substantive Security Council resolution, including those on the admission of new member states or candidates for Secretary - General. The Security Council also has 10 non-permanent members, elected on a regional basis to serve two - year terms. The body's presidency rotates monthly among its members.
Document 2: Hassan Rouhani: Rouhani was deputy speaker of the fourth and fifth terms of the Parliament of Iran (Majlis) and Secretary of the Supreme National Security Council from 1989 to 2005. In the latter capacity, he was the country's top negotiator with the EU three, UK, France, and Germany, on nuclear technology in Iran, and has also served as a Shi'ite ijtihadi cleric, and economic trade negotiator. He has expressed official support for upholding the rights of ethnic and religious minorities. In 2013, he appointed former industries minister Eshaq Jahangiri as his first vice-president.On 7 May 2013, Rouhani registered for the presidential election that was held on 14 June 2013. He said that, if elected, he would prepare a "civil rights charter", restore the economy and improve rocky relations with Western nations. Rouhani is frequently described as a moderate. He was elected as President of Iran on 15 June, defeating Tehran mayor Mohammad Bagher Ghalibaf and four other candidates. He took office on 3 August 2013. In 2013, Time magazine named him in its list of the 100 Most Influential People in the World. In domestic policy, he encourages personal freedom and free access to information, has improved women's rights by appointing female foreign ministry spokespeople, and has been described as a centrist and reformist who has improved Iran's diplomatic relations with other countries through exchanging conciliatory letters. Rouhani won re-election in the 2017 election with 23,636,652 votes (57.1%). He became the third Iranian President, after Mohammad Khatami and Mahmoud Ahmadinejad, to win a presidential victory as an incumbent with an increased electoral mandate.
Document 3: Soviet Union: The Soviet Union suffered greatly in the war, losing around 27 million people. Approximately 2.8 million Soviet POWs died of starvation, mistreatment, or executions in just eight months of 1941 -- 42. During the war, the Soviet Union together with the United States, the United Kingdom and China were considered as the Big Four of Allied powers in World War II and later became the Four Policemen which was the foundation of the United Nations Security Council. It emerged as a superpower in the post-war period. Once denied diplomatic recognition by the Western world, the Soviet Union had official relations with practically every nation by the late 1940s. A member of the United Nations at its foundation in 1945, the Soviet Union became one of the five permanent members of the United Nations Security Council, which gave it the right to veto any of its resolutions.
Document 4: Iran: Since 2005, Iran's nuclear program has become the subject of contention with the international community following earlier quotes of Iranian leadership favoring the use of an atomic bomb against Iran's enemies and in particular Israel. Many countries have expressed concern that Iran's nuclear program could divert civilian nuclear technology into a weapons program. This has led the UN Security Council to impose sanctions against Iran which had further isolated Iran politically and economically from the rest of the global community. In 2009, the US Director of National Intelligence said that Iran, if choosing to, would not be able to develop a nuclear weapon until 2013.
Document 5: Permanent members of the United Nations Security Council: The permanent members of the United Nations Security Council (also known as the Permanent Five, Big Five, or P5) are the five states which the UN Charter of 1945 grants a permanent seat on the UN Security Council (UNSC):
Document 6: Iran–Sudan relations: Iran–Sudan relations refers to diplomatic, economic and military relations between Sudan and Iran. For nearly three decades, Iran and Sudan enjoyed a close relationship. However, Sudan decided to expel all Iranian groups just hours before joining a Saudi military operation in Yemen in March 2015 as the Sudanese President is said to be calculating in favour of his fragile economy in addition to the trauma and horror which struck the Sudanese society when seeing its best and brightest joining the Islamic State of Iraq and the Levant (ISIS) this March, generating a huge public alarm about regional security. The emotional component of protecting Saudi Arabia and walking back to the (Arab house) unfolded dramatically in Arab media. On January 4, 2016 Sudan cut off all diplomatic relations with Iran due to tensions between Saudi Arabia and Iran. As a result, the bond between both countries has severely soured.
Document 7: Iran: The administration continues to follow the market reform plans of the previous one and indicated that it will diversify Iran's oil-reliant economy. Iran has also developed a biotechnology, nanotechnology, and pharmaceuticals industry. However, nationalized industries such as the bonyads have often been managed badly, making them ineffective and uncompetitive with years. Currently, the government is trying to privatize these industries, and, despite successes, there are still several problems to be overcome, such as the lagging corruption in the public sector and lack of competitiveness. In 2010, Iran was ranked 69, out of 139 nations, in the Global Competitiveness Report.
Document 8: Israel and weapons of mass destruction: Israel is widely believed to possess weapons of mass destruction, and to be one of four nuclear-armed countries not recognized as a Nuclear Weapons State by the Non-Proliferation Treaty (NPT). The US Congress Office of Technology Assessment has recorded Israel as a country generally reported as having undeclared chemical warfare capabilities, and an offensive biological warfare program. Officially, Israel neither confirms nor denies possessing nuclear weapons.
Document 9: United Nations Security Council veto power: The United Nations Security Council ``veto power ''refers to the power of the permanent members of the United Nations Security Council to veto any`` substantive'' resolution. A permanent member's abstention or absence does not prevent a draft resolution from being adopted. However, the veto power does not apply to ``procedural ''votes, as determined by the permanent members themselves. A permanent member can also block the selection of a Secretary - General, although a formal veto is unnecessary since the vote is taken behind closed doors.
Document 10: North Korea and weapons of mass destruction: North Korea has a military nuclear weapons program and also has a significant quantity of chemical and biological weapons. As of 2003, North Korea is no longer a party to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). The country has come under sanctions after conducting a number of nuclear tests, beginning in 2006.
Document 11: List of members of the United Nations Security Council: As of July 2011, there are currently 193 members of the United Nations and five permanent members of the Security Council. The other ten seats are assigned amongst the remaining 188 members. As a result, many members have never been on the Security Council. The following list is a summary of all countries, currently 68 modern nations and three historical ones, that have never been a member of the United Nations Security Council. The three historical UN members listed are Tanganyika, Zanzibar, and the Federal Republic of Yugoslavia.
Document 12: Iran: Economic sanctions against Iran, such as the embargo against Iranian crude oil, have affected the economy. Sanctions have led to a steep fall in the value of the rial, and as of April 2013 one US dollar is worth 36,000 rial, compared with 16,000 in early 2012. Following a successful implementation of the 2015 nuclear and sanctions relief deal, the resulting benefits might not be distributed evenly across the Iranian economy as political elites such as the Islamic Revolutionary Guard Corps have garnered more resources and economic interests.
Document 13: Lavizan-Shian: Lavizan-Shian was an alleged undeclared nuclear site north-eastern Tehran, Iran. The site was under investigation by the International Atomic Energy Agency as a potential undeclared nuclear site. According to Reuters, claims by the US that topsoil has been removed and the site had been sanitized could not be verified by IAEA investigators who visited Lavizan. In Paragraph 39 of the IAEA's November 2005 report on Iran, the IAEA stated "The information provided by Iran appeared to be coherent and consistent with its explanation of the razing of the Lavisan-Shian area."
Document 14: United Nations Security Council veto power: The United Nations Security Council ``power of veto ''refers to the veto power wielded solely by the five permanent members of the United Nations Security Council (China, France, Russia, United Kingdom, and United States), enabling them to prevent the adoption of any`` substantive'' resolution. Abstention or absence from the vote by a permanent member does not prevent a draft resolution from being adopted. However, the veto power does not apply to ``procedural ''votes, as determined by the permanent members themselves. The permanent members can vote against a`` procedural'' draft resolution without blocking its adoption by the Council. A negative vote by a permanent member will also block the selection of a Secretary - General, although this is a ``recommendation ''to the General Assembly rather than a Resolution. The unconditional veto posessed by the five governments has been seen by critics as the most undemocratic character of the UN. Critics also claim that veto power is the main cause for international inaction on war crimes and crimes against humanity. However, the United States refused to join the United Nations unless it was given a veto. The absence of the United States from the League of Nations contributed to its ineffectiveness.
Document 15: List of members of the United Nations Security Council: Each year the UN General Assembly elects five new members for a two - year term; these elections always begin in October of the year, and continue until the two - thirds majority for the number of countries for each region has been reached. Re-election is allowed, but the term must not be consecutive.
