<P0-S0> His record in the 5,000 lasted just over 20 years before it was surpassed by French Olympian Michel Bernard. <P0-S1> Nikifor Popov (2 June 1911, in Khabarovsk – after 1980) was a Russian long-distance runner who competed for the Soviet Union in the 1952 Summer Olympics in the 5,000 metres and 10,000 metres as a 40 year old, in the process or qualifying for the Olympics setting the Masters M40 World record in the 5,000 metres and 10,000 metres. <P0-S2> He is reported to have improved upon his own record in the 10,000 three years later. <P0-S3> His 10,000 record was beaten 12 years after the initial setting by another French Olympian, 1956 Marathon gold medalist Alain Mimoun. <SEP> <P1-S0> the end of world war ii brought a baby boom to many countries, especially western ones. <P1-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> <P2-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> <P3-S0> ancient rock paintings in somalia which date back to 5000 years have been found in the northern part of the country, depicting early life in the territory. <P3-S1> the most famous of these is the laas geel complex, which contains some of the earliest known rock art on the african continent and features many elaborate pastoralist sketches of animal and human figures. <P3-S2> in other places, such as the northern dhambalin region, a depiction of a man on a horse is postulated as being one of the earliest known examples of a mounted huntsman. <SEP> <P4-S0> Khabarovsk is served by the Khabarovsk Novy Airport with international flights to East Asia, Southeast Asia, European Russia, and Central Asia. <SEP> <P5-S0> On September 22, 1980, the Iraqi army invaded the Iranian Khuzestan, and the Iran–Iraq War began. <P5-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. <P5-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. <P5-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. <P5-S4> Subsequently, Khomeini accepted a truce mediated by the UN. <P5-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.
