First came the shock, then the horror and now the escalation. Israel's government had been putting the squeeze on the West Bank when the unprecedented attack came from Gaza, stunning the world and targeting the innocent. Seven days later, Israel is dropping leaflets on the Gaza Strip: the prelude to a possible ground offensive.

Would you be willing to risk arrest to stand up for what you believed in? How about 13 times? François Picard invites a panel of journalists to discuss the Nobel Peace Prize going to human rights activist Narges Mohammadi, who's currently serving what amounts to 12 years behind bars in Tehran's notorious Evin prison. From her cell, the 51-year-old activist put out a statement for a prize that's a nod to all those who have risen up since last year's death of Mahsa Amini in the hands of Iran's morality police.

First came the shock, then the exodus. More than three-quarters of Nagorno-Karabakh's estimated 120,000 residents have fled since last week's lightning offensive by Azerbaijan overran the ethnic Armenian enclave. Azerbaijan's military has detained a former commander of Nagorno-Karabakh's separatist forces. That's in addition to Ruben Vardanyan, the former head of Karabakh's separatist government, who was charged with financing terrorism after his arrest while fleeing through the Lachin corridor.

Is it all over in a flash for a conflict that dates back to Soviet times? After winning a war against Armenia in 2020 and following a nine-month blockade of Nagorno-Karabakh, Azerbaijan overrun the enclave on Tuesday in a lightning offensive that offered no choice to Armenian separatists but to lay down their arms and negotiate. For the 120,000 residents of Nagorno-Karabakh, there's a simple question as they look to the future: should they stay or should they go?

This what happens when a failed state meets global warming. An estimated one-tenth of Derna's population is still missing after last Sunday's failure of two 1970s-era dams in the Libyan city. Libya has been divided in half over the past decade by rival factions, meaning that no authority issued warnings over Storm Daniel, which drew on record water temperatures in the Mediterranean to pummel the country with rainfall. Libya's disaster came a day after Morocco's biggest earthquake in a century.

When the week began, it was all about France defying an ultimatum by Niger's coup leaders to recall its ambassador. Now, another precinct has been heard from. A twin surprise came from Gabon overnight on Wednesday, with military brass cancelling the flawed re-election to a third term of President Ali Bongo. Instead, a coup ended a 55-year old father-son dynasty in that oil-rich Central African nation. Quick to emerge from the pack was the head of the Republican Guard, General Brice Oligui Nguema – himself a cousin of the Bongos.

This week's NATO summit was almost a one-man show starring someone whose country is not yet a member of the Alliance: Volodymyr Zelensky. Also this week, Narendra Modi was guest of honour at the Bastille Day military parade in Paris. India's prime minister looked on proudly as Indian soldiers joined the annual July 14 parade down the Champs-Élysées.

Where is Yevgeny Prigozhin? Belarus's president claims he is decamped back to Russia, but no one has seen him in public since that aborted march on Moscow. This as Russian state TV shows images of police raids on his home. Also, could it have gone either way? Senegal's president foregoes a run for re-election, but Macky Sall insists his constitutional reform did not bar him from another term. We ask how much of an outlier that makes him among African leaders. Plus, we discuss the limits of France's colourblind attitude to race.

Yevgeny Prigozhin cheered as he suddenly lifted his occupation of Rostov-on-Don last Saturday night and aborted his Wagner Group's march on Moscow, a challenge unseen by the Kremlin since the failed 1991 coup attempt against Mikhail Gorbachev. Also, France is in shock after a viral video showed a police officer shoot and kill a 17-year-old in the Paris suburb of Nanterre. In scenes reminiscent of the three weeks of rioting back in 2005, nightly clashes have engulfed the country's working class suburbs. There's no state of emergency yet but after calling the killing of Nahel "inexplicable" and "inexcusable", President Emmanuel Macron has turned his sights on the rioters.

For four days, the world waited on word of the tourist submersible and the five people inside who had gone to explore the wreckage of the Titanic. On Thursday, the US Coast Guard announced the tragic news that there were no survivors following a "catastrophic implosion". It wasn't just billionaires aboard: highly respected French explorer Paul-Henri Nargeolet was known as "Mr Titanic" and was part of the early teams that first filmed the wreckage of the ill-fated cruise liner back in 1986.
