On the 70th Anniversary of the day the US dropped the Atomic Bomb on Hiroshima, Japan, Prime Minister Shinzo Abe called for a world without nuclear weapons.  "Seventy years on, I reemphasize the necessity of world peace," Mr. Abe said at the memorial service before 55,000 people from 100 countries gathered at the city's Peace Park, including US Ambassador Caroline Kennedy.  "We have to continue our effort to achieve a world without nuclear weapons.  It is our responsibility and it is our duty."  This comes at a time of concern over Abe's attempts to reinterpret the Japanese constitution to allow for more foreign military missions under the banner of "mutual self-defense".

PM Tony Abbott says searchers are looking in the right place for Malaysia Airlines Flight MH370 - off the west coast - after investigators confirmed that flotsam found on France's La Reunion Island in the Indian is indeed the first debris from the plane that disappeared more than a year ago.  Abbott says locating and identifying the wing flaperon brings the "baffling mystery" closer to being solved.

Searchers in the Mediterranean Sea say they do not expect to find many more survivors of the latest immigrant ship to capsize in the dangerous waters.  The boat with around 600 people on board only made it a few miles off Libya, en route to Europe where the passengers would try to apply for asylum.  The Irish vessel LE Niamh and the Italian Coast Guard rescued about 400 people, but they also recovered only 25 bodies so far.  More than 2,000 would be migrants have drowned in the Mediterranean this year.

Australia has returned 46 asylum seekers to Vietnam, according to Immigration Minister Peter Dutton.  Workers on an oil tanker first spotted their boat 150 kilometers off the west coast last month, and the Navy intercepted the vessel.  Dutton says that over the past 18 months of "Operation Sovereign Borders", authorities stopped 633 people on 20 boats from reaching Australia.

Foreign minister Julie Bishop says Australia's relationship with Indonesia is back on track.  Ms. Bishop went to Kuala Lumpur for the ASEAN summit, and held a meeting with her counterpart Retno Marsudi.  The two worked to get past the diplomatic freeze caused by Indonesia's executions of the Australians Andrew Chan and Myuran Sukumaran in the Bali nine case; and Australia's immigrant boat turn-backs.  Bishop also announced that Trade Minister Andrew Robb will soon lead a bevy of Australian businessmen to Indonesia.

A court in Brazil sentenced two prominent construction executives to prison for corruption as part of the scandal at the state-owned oil company Petrobras.  Prosecutors successfully convinced the court that Jose Aldemario Pinheiro and Agenor Medeiros were found guilty of bribing government officials, money laundering and conspiracy to commit crimes.  The scandal has reached into the highest levels of government and caused a massive erosion of President DilmaRousseff's popularity.

Former Prime Minister Julia Gillard has taken out newspaper advertisements to apologize for untrue claims made about the university days of Senator Nick Xenophon in her autobiography, "My Story".  In the book's edition, Gillard says Xenophon was temporarily excluded from university for stuffing a ballot box.  She now says her recollection was faulty:  "I retract the allegation, accept that the allegation was false, and sincerely apologise to Nick Xenophon for any harm, embarrassment and distress caused," Ms Gillard said.  Xenophon told Newscorp that he was glad it was over: "I'm glad she agreed to the apology and I wish her well," said Xenophon.
