Hiroshima, Japan, Aug 6, SPA -- Tens of thousands of people from around the world gathered in Hiroshima on Saturday to renew calls for the abolition of nuclear arms on the 60th anniversary of the atomic bombing of the city, Reuters reported. Under a blazing summer sun, survivors and families of victims assembled at the Peace Memorial Park near "ground zero", the spot where the bomb detonated on Aug. 6, 1945, killing thousands and levelling the city. The anniversary comes as regional powers meet in Beijing to urge North Korea to give up its nuclear programme, seen by Tokyo as a threat and one of the reasons behind rising calls in Japan to strengthen its defence and seek closer military ties with the United States. Prime Minister Junichiro Koizumi was among those attending the ceremony in Hiroshima, 690 km (430 miles) southwest of Tokyo. At 8:15 a.m., the time when the U.S. B-29 warplane Enola Gay dropped the bomb, people at the park and throughout the city observed a minute's silence in memory of those who perished. Bells at temples and churches rang and passengers on the streetcars that run throughout the city bowed their heads in remembrance of the dead, including those incinerated while riding the streetcars. "This Aug. 6 ... is a time of inheritance, of awakening, and of commitment, in which we inherit the commitment of the bomb victims to the abolition of nuclear weapons and realisation of genuine world peace," Hiroshima mayor Tadatoshi Akiba told the gathering. --mor 1335 Local Time 1035 GMT www.spa.gov.sa/281528
