Two people died and four are missing after the collapse of an ancient pagoda that was recently used for a ceremony led by the wife of Myanmar's junta leader, police said Sunday. Police said another 45 people were injured when the Danok pagoda in Dalla township, just across a river from the main city of Yangon, fell down on Saturday after two days of heavy rain. 'We do not know the cause of the collapse,' a police officer said on condition of anonymity, updating an earlier toll of 30 injured. Authorities using mechanical diggers began clearing the debris from the scene on Sunday, witnesses said, adding that the pagoda had collapsed without warning. Rescuers from the army, navy, police, fire brigade and local Red Cross all took part in the operation on Saturday to pull survivors from the wreckage of the temple. The tiered tower was on May 7 the site of a ceremony involving the wife of the reclusive top leader of Myanmar's military regime, Senior General Than Shwe. Kyaing Kyaing led the event, hoisting a diamond orb to the top of the pagoda, situated about 30 kilometres (20 miles) from Yangon. Danok Pagoda, famous in Myanmar because it enshrines two sacred Buddhist relics, was damaged during Cyclone Nargis in May last year and recently underwent reconstruction. Myanmar, which has been ruled by the military since 1962, is a predominantly Buddhist nation.
