World's last male northern white rhino dies; could spark extinction crisis

Researchers say the world's last male northern white rhino, Sudan, has died after "age-related complications." A statement from the Ol Pejeta Conservancy in Kenya says the 45-year-old rhino was euthanized yesterday after his condition "worsened significantly" and he was no longer able to stand.

The rhino had been part of an ambitious effort to save the subspecies from extinction with the help of the two surviving females.

"He was a great ambassador for his species and will be remembered for the work he did to raisConservancy'slobally of the plight facing not only rhinos, but also the many thousands of other species facing extinction as a result of unsustainable human activity," said the conservancy's CEO, Richard Vigne.

Sudan was something of a celebrity, attracting thousands of visitors.

African countries should weigh Chinese loans carefully: Rex Tillerson

US Secretary of State Rex Tillerson said on Thursday that African countries should be careful not to forfeit their sovereignty when they accept loans from China, the continent's biggest trading partner.

Tillerson is using his first diplomatic trip to the continent to bolster security alliances on a continent increasingly turning to Beijing for aid and trade.

He may also seek to smooth relations after US President Trump reportedly dismissed some African nations as "shithole countries" in January. Trump later denied making the comment.

"We are not in any way attempting to keep Chinese dollars from Africa," Tillerson told a news conference in the Ethiopian capital. "It is important that African countries carefully consider the terms of those agreements and not forfeit their sovereignty."
