Good Morning Australia!! - An ominous signal from Tehran - A key US military base is undercut by the UN - UK voters could get a second chance at the Brexit - And more in your CareerSpot Global News Briefs:

A sign from Iran that things could be getting a lot more difficult:  Foreign Minister Mohammad Javad Zarif has resigned, according to the state-run IRNA news agency.  This followed a social media post in which he offered an "apology" for his "inability to continue to his service".  Zarif was the driving force behind Iran's 2015 nuclear deal with world powers that finally got Tehran to give up its nuclear ambitions in exchange for relief from economic sanctions.  However, the Trump administration took it upon itself to undo the world's progress which left the deal near collapse.  Zarif's resignation might be an indication that the hard-liners are reasserting control in Tehran.

The United Nations International Court of Justice has ruled that the UK should end its control of the Chagos Islands in the Indian Ocean "as rapidly as possible".  Mauritius claims it was forced to give up the islands in 1965 in exchange for independence from British colonization in 1968, and the court agrees.  London issued a "nyah nyah we don't have to" statement reading, "This is an advisory opinion, not a judgment."  The Chagos Islands are the site of the UK's Diego Garcia Naval Support Base, a key installation in the so-called "war on terror" - the UK leases it to the US, which uses it to project western hegemony on southern Asia.  Along with the US base on Guam, it makes up to the two most important western facilities in the region.

Donald Trump delayed his planned tariffs on billions of dollars worth of Chinese imports, which were to take effect on Friday.  He claimed "substantial progress" in trade talks between the two nations.  While Trump is traveling to Vietnam for another summit with Kim Jong-un of North Korea, he's also trying to get Chinese President Xi Jinping to come to his garish Florida retreat Mar-a-Lago for a summit. 

UK Labour will support a second referendum on the Brexit, if its counter-proposal on handling the divorce from Europe is rejected in Parliament later this week.  It's a somewhat of a turnaround for leader Jeremy Corbyn, who had been previously lukewarm on the idea.  A party memo says that any such referendum would have two choices - to Remain in the European Union, or a "credible" option to Leave that would contain specifics on how it would happen.  PM Theresa May says he efforts will be directed towards the current Brexit date, 29 March.

Nigeria's ruling party is denying the main opposition's accusation of vote-rigging in the country's delayed elections.  The party backing opposition candidate Atiku Abubakar claims agents hacked into the electoral commission's server and created "incorrect, thus unacceptable" election results.  The ruling party of President Muhammadu Buhari is ahead in the preliminary vote count.

Nearly 87 percent of Cuban voters approved a new constitution - that's a bit lower than expected, since President Miguel Diaz-Canel and his predecessor Raul Castro each received 94 percent approval in their last elections.  The new document maintains single party rule and the centrally-planned economy, while updating some criminal and electoral codes.  The largest bloc of "No" votes came from evangelical christians who opposed reforms that could lead to legalized same-sex marriage.
