Good Morning Australia!! - Mail bombs target Obama, Hillary, and others sharing a common trait - Putin warns of a new arms race - MBS talks about Khashoggi - And more in your CareerSpot Global News Briefs:

US investigators are determining the source of six pipe bombs that were sent in the US Mail to several prominent people:  Barack Obama, Hillary and Bill Clinton, billionaire financier George Soros, former CIA chief John Brennan, former Attorney General Eric Holder, and Congresswoman Maxine Waters - all prominent critics or opponents of Donald Trump.  Some of the bombs may have been hand-delivered, but none made it to their intended targets, and none exploded.  The packages intended for Hillary and Obama were caught at a military base that screens mail for current and former US Presidents.  The US Capitol post office caught the device meant for Ms. Waters.

But the bomb meant for Mr. Brennan was sent to CNN where he is a frequent guest on news broadcasts, and that's a story within itself.  While news readers Jim Sciutto and Poppy Harlow were live on-air talking about the earlier bombs, alarms started going off in the CNN newsroom behind them and personnel could be seen exiting as authorities evacuated the Time Life Building in Manhattan.  After a slightly longer-than-usual commercial break, Harlow and Sciutto resumed their broadcast from the sidewalk, using cell phones and Skype instead of a multi-million dollar TV studio. 

The package bomb meant for Mr. Holder revealed more about the bombers' sick sense of humor.  It was mislabeled and undeliverable, and so it was sent back to the return address - the district office for Florida Congresswoman Debbie Wasserman-Schultz, a former head of the Democratic National Committee.  Whether this was a mistake on the part of the bomber, or an attempt to have the package skip through Ms. Wasserman-Schultz's security is not clear.  One of those bomb-disposing robots took care of it.  She later released a statement condemning the attempted bombings and making clear she "didn't appreciate the way her name was being used".

Anyway..

Russian President Vladimir Putin is warning Europe not to install US nuclear missiles, or he will respond "in kind".  This comes after Donald Trump accused Russia of violating the 1987 Intermediate-Range Nuclear Forces (INF) treaty by developing a new medium-range missile called the Novator 9M729; Trump announced plans to pull the US out of the deal.  Putin said it was "very dangerous" to dismantle a global arms control system and added, "There would be nothing left except an arms race." 

Saudi Crown Prince Muhammad bin Salman (MBS) is vowing to punish all the "culprits" responsible for the murder of dissident journalist Jamal Khashoggi in the Saudi consulate in Istanbul, Turkey.  After weeks of shifting explanations - and for the first time since Saudi Araboa admitted that Khashoggi was killed inside the continent - MBS said "the crime was painful to all Saudis" but he would never allow any rift with Turkey.  Most Western intelligence sources tend to support Turkey's claim that a Saudi hit team tortured and dismembered Mr. Khashoggi after he entered the consulate on 3 October to sign some papers; many suspect that MBS himself ordered the killing.  Riyadh denies that.

Nigeria's finance minister says the government will not put a cap on how many children a woman can have.  The rumor mill started going a little crazy after Zainab Ahmed said the government had been engaging traditional rulers and religious organisations on how to tackle Nigeria's growing over-population problem.  Ms. Ahmed says that means convincing women to wait a while in between pregnancies.  As things stand now, Nigeria is on track to become the world's most-populous nation after China and India by the middle of the century.
