Fentanyl is deadly. Thousands of Americans die every year from a drug overdose – the majority of them after using a synthetic opioid like fentanyl. It was developed as a legal, and effective, pain killer. Now, fuelled by insatiable US demand, it is illicitly produced in makeshift laboratories in Mexico by organised crime groups. In the first part, Assignment travels to the Mexican Pacific port of Manzanillo. This is one of the main entry points for the chemical ingredients required to make fentanyl. It is a town where Mexico’s powerful cartels have fought for control, and where the mayor lives under armed guard after a failed assassination attempt. In the second part, we cross the border into the US from Mexico to explore the devastation this lethal drug has left in its wake in San Diego County.

Over the summer, a mysterious Twitter persona published details of over 14,500 social media accounts - all of them controlled by real-life Serbian citizens, it's claimed. They stand accused of posting… whatever the President’s party tells them to.It’s long been rumoured that Serbia’s ruling SNS party commands the online activity of a small army of citizens, dubbed ‘bots’ by the opposition. But this kind of list, naming and shaming thousands of ordinary Serbians, is unprecedented.If true, their activity represents a form of political corruption according to Serbia’s public prosecutor. The government’s response has alarmed observers - it shrugged off the story, publishing instead a veiled tongue-in-cheek ‘admission’.But who is behind the list, and can it be trusted? BBC Trending has analysed the data in an attempt to establish if the ‘bots’ are indeed real people. And whether their accounts show evidence of co-ordinated activity.Featuring interviews gathered on the ground in Belgrade, we hear from opposition politicians, pro-democracy activists and a self-professed real-life ‘bot’. She tells us she trolled the President’s opponents under threat of losing her job – as a receptionist at a state-controlled electricity company in a small Serbian town.Reporter: Sam Judah

Modern Cairo is a crowded metropolis. The city’s ‘thousand minarets’ are now dwarfed by a new skyline of slick tower blocks. Modern highways fly over bustling kiosks where residents gather to smoke and buy soda drinks. Inspired by the lives of their neighbours, playing out among mosques, high rise buildings and on busy streets, Egyptian writers and graphic artists, including Deena Mohamed, Shennawy and Mohamed Wahba bring their thousand-year-old capital to life.
