Emergency crews responded to a "major incident" at the Don Dale Youth Detention Center in Northern Territory.  This includes police, ambulance officers, and firefighters who battled at least one fire that appeared to do heavy damage.  Young people were seen on the roof of one of the other buildings at one point.  The ABC quoted the loudspeaker warning to detainees:  "This is the police.  Drop your weapons.  Your actions are being monitored.  There will be consequences.  Stop putting yourself and others at risk.  Surrender yourself to the police."  Two days earlier, officials were in a lengthy stand off with two youths who climbed to the roof of one of the buildings.  It's the latest and possibly the most-serious incident at the troubled facility, which was the subject of an ABC investigation in 2016 that revealed abuse of Aboriginal teens there.

Cameroon's military spread out in the northwest to search for 79 students and three adults kidnapped from a boarding school in Bamenda, the regional capital.  French-speaking government officials blamed English-speaking separatist militias for the kidnapping, but the rebels say the government staged the mass abduction to discredit their cause.

UN investigators say the so-called Islamic State left more than 200 mass graves containing as many as 12,000 bodies of victims in Iraq.  "The mass grave sites documented in our report are a testament to harrowing human loss, profound suffering and shocking cruelty," said Jan Kubis, the UN Secretary General's special representative for Iraq.  But they will also be critical for gathering evidence of atrocities against IS.

A group of mothers of the missing are leading a dig in Mexico's Veracruz state, where the drug cartels known as Los Zetas and Jalisco New Generation are at war with each other.  Hundreds of bodies have been found in shallow graves over the last couple of years; the fear now is that the site has more than 400 bodies.  "It was a killing field, or worse," said a spokeswoman for the mothers' group Solecito.

French police arrested six people in an alleged plot to commit a "violent action" against French President Emmanuel Macron.  Local media reports the five men and one woman are linked to far right groups.  Officials describe the plot as "imprecise and ill-defined at the moment" indicating they caught it very early.  Authorities have previously disrupted far-right plots to murder Leftist leaders and to use terrorism to prompt migrants to leave the country.

The trial has begun for a 94-year-old former SS guard accused of complicity in the Holocaust.  Johann Rehbogen denies knowledge of mass murders at the Stutthof camp in what is now northern Poland from June 1942 to September 1944.  Despite his advanced age, the wheelchair-bound Rehbogen is being tried in a juvenile court in Munich because he was not yet 21-years old at the time of the atrocities.

British police arrested five men for a really awful stunt; they made a mock-up of the Grenfell Tower to burn for Guy Fawkes Day.  The video they made went viral on social media and provoked outrage around the world.  All five were arrested on "suspicion of a public order offence" which gives cops broad discretion in intentional "harassment, alarm or distress" caused via the use of "threatening, abusive or insulting" words or signs.  More than 70 people died in the real horror fire at Grenfell Tower in June last year.
