As the sun sets behind the Dhaar mountains and the desert air cools, the streets of Oualata fill with the sounds of children at play, and the ancient town briefly springs back to life.

The announcement of the arrests came hours after officials said five bodies had been found in the search for the men, who were members of a local band called Fugitivo.The musicians were hired to put on a concert on Sunday but arrived to find that the location of their proposed performance was a vacant lot, according to family members who had held a protest urging the authorities to act.

Relatives had reported receiving ransom demands for the musicians, who were aged between 20 and 40 years old.Mexican musicians have been targeted previously by cartel members amid rivalry, as some receive payment to compose and perform songs that glorify the exploits of gang leaders.Investigators used video surveillance footage and mobile phone tracking to establish the musicians’ last movements, Barrios said.

Nine firearms and two vehicles were seized, he said.More than 480,000 people have been killed in drug-related violence and organised crime, and about 120,000 people have gone missing, in Mexico.

At least 3,018 people displaced and 265 houses destroyed in the floods in central Nigeria as more rains are feared.

More than 150 people have been killed and thousands displaced after floods devastated parts of central Nigeria, local authorities said, as rescue teams continue to recover bodies and search for the missing.“Which map projection did you use?” she asked, referring to the method of representing maps on a flat plane.

The sellers never responded, but Ogundairo suspected they used a problematic projection. Discouraged, she refused to place an order.Ogundairo’s obsession with map projections is not random. The 28-year-old is leading an African-led campaign to get more of global institutions and schools to immediately stop using the Mercator Map projection – the most common version of the world map that is generally recognised – because it shrinks Africa, and much of the Global South, while disproportionately enlarging the rich and powerful regions of the world.

Greenland, for example, is shown to be relatively the same size as Africa, but, in reality, can fit in the continent 14 times over. Europe, portrayed as bigger than South America, is actually half its size.Advocates like Ogundairo are pushing instead for “equal area” map projections, which they say more accurately represent the prominence of the African continent.
