An exhibition based on the 1945 A-bombing of Nagasaki began Monday in Khartoum to inspire a country hit by a decades-long civil war that killed 2 million people before it ended in 2005.

"We want to convey to Sudanese people how Nagasaki recovered from the atomic bombing," said Naoyuki Kawahara, 47, a physician representing the nonprofit group Rocinantes that organized the display of about 40 photographs, including those of the mushroom cloud, at the University of Khartoum campus through Thursday.

Kawahara was named Nagasaki peace messenger after he took Sudanese kids in summer 2011 to the city's atomic bomb museum and quake- and tsunami-hit parts of the Tohoku region.
