Good Morning Australia!! - North Korea says it is not kidding around with its nuclear ambitions - Authorities identify what is stalling the investigation into the Las Vegas Massacre - Some sport fans in Italy need a history lesson - And more in your CareerSpot Global News Briefs:

North Korea is warning the world to take it seriously when it says it might conduct an open-air nuclear weapon test in the Pacific Ocean.  Senior official Ri Yong Pil told CNN that the North "has always brought its words into action".  Last month, Foreign Minister Ri Yong Ho raised the possibility of a blast over the Pacific, and Donald Trump responded by threatening to "totally destroy" the North.  North Korea carried out the strongest of its six-ever nuclear tests in early September.  The US, UK, and Soviet Union signed a deal to stop atmospheric nuclear tests in 1964, France continued until 1974, and China had its last open air nuclear weapon test in 1980.

The investigation into the Las Vegas massacre has been stymied because a hard drive is missing from a computer belonging to gunman Stephen Paddock, which was in the hotel room when he opened fire on people attending a country music below killing 58 and wounding more than 500.  The absence of a digital footprint has left investigators struggling to establish a motive.  Meanwhile, a third Paddock brother named Bruce - not the guy in Florida who gave interviews after the shooting, but a destitute squatter in Los Angeles - has been arrested for allegedly possession child pornography.

Pianist Fats Domino, who is associated as much with the birth of Rock and Roll as with the music of New Orleans - is dead at age 89.  His hits were often characterized by pounding piano chords in a triplet rhythm, and include "Ain't That A Shame" and "Blueberry Hill".

Authorities suspect arson as the cause of a bushfire that destroyed about a quarter of Brazil's Chapada dos Veadeiros national park, a UNESCO World Heritage site in Goias state.  About 54,000 hectares have burned in the park which is noted for its rich biodiversity.

Brazil President Michel Temer was rushed to hospital because of a blocked uninary tract.  His office said Temer underwent a bladder video test by catheter and was expected to leave the hospital the same day.  It comes as Congress was to vote on whether he will face a corruption trial.  The body is controlled by Temer's allies and two months ago voted against a corruption trial on different charges.

Venezuelan opposition leader Henrique Capriles has quit the opposition coalition after four of its newly elected governors pledged allegiance to the new Constituents Assembly formed by direct democratic election.  The conservative Capriles is a former presidential candidate, having lost to both Socialists Hugo Chavez and Nicolas Maduro. 

Kenya holds its Presidential election re-run today, although the main opposition candidate Raila Odinga is urging his followers to boycott the poll.  President Uhuru Kenyatta is seeking a second term; he won the election in August, but the courts ordered a repeat because of alleged irregularities.  The campaign between the two polls has seen a lot of violence, including shootings and murders.

All of this Sunday's soccer matches in Italy will be preceded with a history lesson:  Passages from The Diary of Anne Frank will be read.  This is after a contingent of Lazio fans - racists known as "ultras" - posted stickers of the Holocaust victim wearing a Team Roma jersey alongside anti-Semitic slogans.  Lazio and Roma share Rome's Olympic Stadium.  Sports Minister Luca Lotti said those responsible for last Sunday's racist vandalism would be "identified and punished", adding: "There is no justification. These are instances to be condemned unconditionally."  Weekday matches are already being preceded by giveaways of the Anny Frank Diary.

Don't we all, Woody Harrelson.  Don't we all.
