A total of 3,916 war-left shells of 11 kinds have been unearthed recently in Myanmar\'s Mohnyin township, official media reported Friday. The shells were dug out from about one meter deep in the ground at a location between two government offices in the area throughout the past two weeks amid rain, the New Light of Myanmar said. Local aged residents were quoted as saying that Japanese troops left a number of scattered ammunition while withdrawing from Myanmar after losing the Second World War and local police stations had then collected and buried those ammunitions supposed to prevent them from getting into the hands of rebels and thieves. In March this year, a cannon, identified to have been left by the Second World War, was also found at an extended road project site in Myanmar\'s former capital of Yangon. The war-left cannon of a length of over 3 meters with a diameter of 1.2 meters at the front and 0.4 meter at the rear was discovered when the ground was dug in the course of work with the extension of the Strand Road along the bank of Yangon river. The unearthed cannon was managed to be displayed at the National Museum. Moreover, in June 2009, a thickly-rusted hand grenade, suspected to be left by the war, was also discovered in a construction site in Yangon. The grenade was unearthed by workers when they were digging deep below in the city\'s Bahan township to start construction of a new building.
