Question: How many states does the organization who mediated the truce ending the Iran-Iraq War recognize in the continent where Ivan Koumaev was born?

full_context: Document 1: Mimi Kuzyk: Kuzyk was born in Winnipeg, Manitoba to Fred and Kay Kuzyk, both of whom are Ukrainian immigrants, and received her early education at the Immaculate Heart of Mary School. She danced with the Rusalka Ukrainian dance group in Winnipeg for 12 years and briefly studied jazz dance at the Royal Winnipeg Ballet School.
Document 2: Korean Air: Korean Air's international passenger division and related subsidiary cargo division together serve 127 cities in 44 countries, while its domestic division serves 12 destinations. It is among the top 20 airlines in the world in terms of passengers carried and is also the top-ranked international cargo airline.

Document 4: Near East: The United Nations formulates multiple regional divisions as is convenient for its various operations. But few of them include a Near East, and that poorly defined. UNICEF recognizes the "Middle East and North Africa" region, where the Middle East is bounded by the Red Sea on the west and includes Iran on the east. UNESCO recognizes neither a Near East nor a Middle East, dividing the countries instead among three regions: Arab States, Asia and the Pacific, and Africa. Its division "does not forcibly reflect geography" but "refers to the execution of regional activities." The United Nations Statistics Division defines Western Asia to contain the countries included elsewhere in the Middle East. The Food and Agriculture Organization (FAO) describes its entire theatre of operations as the Near East, but then assigns many of its members to other regions as well; for example, Cyprus, Malta and Turkey are in both the European and the Near Eastern regions. Its total area extends further into Central Asia than that of most agencies.
Document 5: Iran: On September 22, 1980, the Iraqi army invaded the Iranian Khuzestan, and the Iran–Iraq War began. Although the forces of Saddam Hussein made several early advances, by mid 1982, the Iranian forces successfully managed to drive the Iraqi army back into Iraq. In July 1982, with Iraq thrown on the defensive, Iran took the decision to invade Iraq and conducted countless offensives in a bid to conquer Iraqi territory and capture cities, such as Basra. The war continued until 1988, when the Iraqi army defeated the Iranian forces inside Iraq and pushed the remaining Iranian troops back across the border. Subsequently, Khomeini accepted a truce mediated by the UN. The total Iranian casualties in the war were estimated to be 123,220–160,000 KIA, 60,711 MIA, and 11,000–16,000 civilians killed.
Document 6: Gulf War: The Gulf War (2 August 1990 -- 28 February 1991), codenamed Operation Desert Shield (2 August 1990 -- 17 January 1991) for operations leading to the buildup of troops and defense of Saudi Arabia and Operation Desert Storm (17 January 1991 -- 28 February 1991) in its combat phase, was a war waged by coalition forces from 35 nations led by the United States against Iraq in response to Iraq's invasion and annexation of Kuwait.

Document 8: Invasion of Kuwait: The Invasion of Kuwait on 2 August 1990 was a two - day operation conducted by Iraq against the neighboring state of Kuwait, which resulted in the seven - month - long Iraqi occupation of the country. This invasion and Iraq's subsequent refusal to withdraw from Kuwait by a deadline mandated by the United Nations led to military intervention by a United Nations - authorized coalition of forces led by the United States. These events came to be known as the first Gulf War and resulted in the expulsion of Iraqi forces from Kuwait and the Iraqis setting 600 Kuwaiti oil wells on fire during their retreat.

At present, about 22 international airlines connect Nepal to other destinations in Europe, Asia and the Middle East, to cities such as Istanbul, Delhi, Kolkata, Singapore, Bangkok, Kuala Lumpur, Dhaka, Islamabad, Paro, Lhasa, Chengdu, and Guangzhou. A recent extension to the international terminal has made the distance to the airplanes shorter and in October 2009 it became possible to fly directly to Kathmandu from Amsterdam with Arkefly. Since 2013, Turkish Airlines connects Istanbul to Kathmandu. Regionally, several Nepali airlines operate from the city, including Agni Air, Buddha Air, Cosmic Air, Nepal Airlines and Yeti Airlines, to other major towns across Nepal.
