The headquarters of the BBC is Broadcasting House in Portland Place, London. The BBC also has other offices such as the BBC Television Centre in White City, London, BBC Radio Berkshire, as well in other cities like Cardiff, Belfast, Glasgow, Birmingham, Manchester, Bristol, Southampton and Newcastle upon Tyne. Rather than hire local reporters everywhere, the BBC's journalists work in many countries across the world. This means BBC workers are sometimes in danger, especially in war zones. Most recently Alan Johnston was kidnapped and held hostage for many months in Gaza before being safely released.
