In 2009, three American hikers were arrested and jailed after they crossed an unmarked border into Iran while on holiday in Iraqi Kurdistan. Sarah Shourd was released first and fought a long campaign to get her friends Shane Bauer and Josh Fattal released from prison in Teheran. Their freedom was eventually brokered by diplomats from Oman – opening up a diplomatic channel between Iran and the US which was later used in their nuclear negotiations.

A group of Californian nuns left their convent and set up their own independent community in 1970. They’d been inspired by the social change they saw around them in Los Angeles in the 1960s, and the Pope's promise to modernise the Catholic Church. They wanted to stop wearing their traditional habit and abandon their set prayer times, but their conservative cardinal refused to discuss change. So three hundred of the sisters left to set up their own lay community – the Immaculate Heart Community, which is still running today. Former Sister Lucia Van Ruiten tells Witness History about the crisis they caused in the Catholic church.

An insider's account of Project Babylon, the plan to build the largest gun in the world for Saddam Hussein's Iraq. The "Supergun" was the brainchild of Canadian artillery maverick, Dr Gerald Bull. He'd long wanted to build a gun capable of launching satellites into space. In the 1980s Saddam Hussein agreed to fund this plan. But was it a science project or a weapon?
