Japan on Friday (August 9) marked the atomic bombing of the southern city of Nagasaki 68 years ago in the last days of World War Two.

At a solemn ceremony on Friday morning, a bell tolled at 11:02 a.m. local time (0202 GMT), the exact time the bomb was dropped.

More than 150,000 died in the attack and from the subsequent radiation sickness.

But Mayor of Nagasaki, Tomihisa Taue, criticised the Japanese government's refusal to sign a non-proliferation treaty earlier in the year.

The United States dropped the atomic bomb on Hiroshima on August 6 1945 and Nagasaki on August 9. Japan surrendered six days later, ending World War Two.
