Question: For the continent where Sergei Kruglov was born, how many countries are recognized by the institution that mediated the end of the Iran-Iraq War?

<P0-S0> Sergey Andreyevich Kruglov (also Sergei Kruglov, ; born March 27, 1985 in Khabarovsk) is a Russian sport shooter. <P0-S1> In 2010, Kruglov had won a gold medal for the 10 m air rifle at the European Shooting Championships in Meråker, Norway, and eventually captured the bronze at the ISSF World Cup in Fort Benning, Georgia, United States. <P0-S2> He is also a member of CSA Pomoriye and is coached and trained by Oleg Seleznev. <SEP> <P1-S0> On September 22, 1980, the Iraqi army invaded the Iranian Khuzestan, and the Iran–Iraq War began. <P1-S1> 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. <P1-S2> 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. <P1-S3> 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. <P1-S4> Subsequently, Khomeini accepted a truce mediated by the UN. <P1-S5> 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. <SEP> <P2-S0> the end of world war ii brought a baby boom to many countries, especially western ones. <P2-S1> there is some disagreement as to the precise beginning and ending dates of the post-war baby boom, but it is most often agreed to have begun in the years immediately after the war, though some place it earlier at the increase of births in 1941 - 1943. the boom started to decline as birth rates in the united states started to decline in 1958, though the boom would only grind to a halt 3 years later in 1961, 20 years after it began. <SEP> <P3-S0> Khabarovsk is served by the Khabarovsk Novy Airport with international flights to East Asia, Southeast Asia, European Russia, and Central Asia. <SEP> <P4-S0> the African Group, with 54 member states the Asia - Pacific Group, with 53 member states the Eastern European Group, with 23 member states the Latin American and Caribbean Group (GRULAC), with 33 member states the Western European and Others Group (WEOG), with 28 member states, plus 1 member state (the United States) as an observer state. <SEP> <P5-S0> united states support for ba'athist iraq during the iran -- iraq war, against post-revolutionary iran, included several billion dollars' worth of economic aid, the sale of dual - use technology, non-u.s. origin weaponry, military intelligence, and special operations training. <P5-S1> at no point, however, did the u.s. directly supply arms to iraq. <P5-S2> of particular interest for contemporary iran -- united states relations are the repeated accusations that the u.s. government actively encouraged iraqi leader saddam hussein to invade iran (proponents of this theory frequently describe the u.s. as having given saddam a ``green light ''), supported by a considerable amount of circumstantial evidence, but the u.s. government officially denies that any such collusion occurred, and no conclusive proof of it has been found by scholars that have studied the issue.
