Zimbabweans celebrated in the streets after President Robert Mugabe finally took the hint and resigned as his former allies in government were about to impeach him.  The 93-year old said the decision was voluntary and he had made it to allow a smooth transfer of power.  Mugabe had ruled Zimbabwe for 37 years, but upset the apple cart when he sacked his vice president and appeared to be clearing the way for his 50-year old wife Grace to assume power.  Opposition leaders were cautious:  Some warned that Zimbabwe had "removed a tyrant but not yet a tyranny" referring to the ruling Zanu-PF Party, while others called for dialogue, and free and fair elections.

Mugabe's nearly four decades in power will be remembered by supporters as a victory over colonial rule.  But the revolutionary spirit if 1980 was quickly replaced by often-gruesome repression, violence, and rampant corruption.  The Australian High Commission believed that Mugabe was responsible for massacres of rival revolutionary groups in Matabeleland during the 1980s.  The forcible acquisition of farms owned by the descendants of white settlers wound up with the land not distributed to local people, but to political elites and the Mugabe clan.  2008 saw violence crackdowns on any meaningful opposition to preserve Mugabe family power.  And as the dictator leaves office with most of his citizens poor, he takes with him around US$1 Billion in assets plundered from his country and invested in everything from Hong Kong real estate to Scottish Castles.

At least 50 worshipers were killed in a suicide blast at a mosque in the eastern Nigerian state of Adamawa.  The blast went off during morning prayers when the mosque was packed.  Boko Haram is suspected.

Argentina's Navy says its missing submarine ARA San Juan might soon run out of oxygen, adding urgency to the search for the vessel and its 44-member crew.  The worst case scenario is for the air to run out by Wednesday.  Argentine navy spokesman Enrique Balbi said, "The search area is two times the size of Buenos Aires," and that vessels from seven nations are taking part in the search.  The captain reported an electrical failure during the last communication from the ARA San Juan on 15 November.

Russia is denying that it had a nuclear accident in late September, while acknowledging that it had measured pollution of the isotope ruthenium-106 at nearly a thousand times normal levels in the Ural mountains near the Mayak nuclear power plant.  These measurements confirm an earlier French report of high radiation levels in the Urals.  Ruthenium-106 does not occur in nature, it is the product of splitting atoms in a reactor and does not occur naturally.  Medically it is used for cancer radiation therapy, especially for eye and skin tumors - and is also found in the generators that power satellites.

Vladimir Putin hosted Syrian President Bashar al-Assad in a surprise gathering in Sochi, announcing that the Russian military campaign in the Middle Eastern nation was wrapping up.  The intervention has given Assad the upper hand against the so-called Islamic State and and other rebel groups whose support from the West has ebbed since Donald Trump infested the White House.  Later, Putin called his employee in the White House to debrief him on the plan.  Donald Trump later said it was a "great call", claiming Putin spoke "very strongly about bringing peace to Syria" and "very strongly about North Korea."
