When Chinese policeman Dong Guangping wrote an article commemorating the 10th anniversary of the 1989 military crackdown on pro-democracy protesters in Beijing, it kicked off a chain of events that led to him serving jail time and losing his job. But it also sparked the beginning of a deep desire to live more freely. So Dong began planning how he might escape China. Just a few weeks ago, back in late May, he finally achieved his dream, having taken the huge risk of crossing China's Yellow Sea in a dinghy to reach South Korean waters. Phoebe Kong, based in the BBC's Hong Kong bureau, explained how rare Dong's achievement really is.

What does it mean to inherit a faith that served as a fortress for your father, but feels like a contradiction to you? Throughout his childhood in Oxford, Silas Gray was surrounded by the sights, sounds, and symbols of his father’s Rastafarian identity. He was even named after the Rastafarian spiritual figurehead, Emperor Haile Selassie I.

But this legacy weighs heavily. It anchors him to a complex world leader he’s not sure he’s aligned with. And he feels like an imposter carrying a name associated with a faith he doesn’t practise.

Desperate to find a version of this legacy he can comfortably own, Silas decides to do what his father spent forty years dreaming of but never actually did: he books a flight to Ethiopia and travels to the Rastafarian spiritual motherland of Shashamane, the land granted to the global black diaspora by the Emperor himself.

Silas encounters a living, breathing community where three generations of Rastafarians exist under one roof.

This is a deeply personal pilgrimage about a son trying to see what his father sees, heal a generational disconnect, and finally make peace with his name.

The 1st of July 1916 is still one of the deadliest days in the history of warfare. Nearly 20,000 men from the British Army and 6,000 German soldiers were killed on the first day of the Battle of the Somme. The World War One battle would last another four months and was one of the first examples of industrial warfare; three million men fought in it, over a-million soldiers were wounded, missing or killed. Jordan Dunbar investigates how, 110 years on, the battle still affects people and communities, and discovers new insights about its impact on his own family and on the history of Ireland.
