A picture that has racked up thousands of shares on Facebook and Twitter claims to show the oldest tortoise in Africa who -- supposedly -- recently died aged 344. But the picture actually shows a giant Galapagos tortoise, nowhere near as old, in an Australian zoo.

A hoax message claiming that jihadists from the Islamic State group are masquerading as medics offering people free blood tests -- while actually injecting them with the HIV virus -- has been circulating in various countries since 2017. The hoax, which has previously spread everywhere from India and Nepal to Ghana, has re-emerged recently in Kenya alongside a claim that three people were arrested over the plot in the city of Kisumu. However, Kenya police told AFP the security alert was “untrue”. Nepalese and Indian police have previously also warned people that the message was false.
