A manhunt is underway after at least one person was killed and three police staff were shot and wounded at a free speech debate in Copenhagen.

An audio recording obtained by the BBC captures the moment the gunmen interrupted the event at the Krudttoennen cafe in the Oesterbro district of the city.

Controversial Danish cartoonist Lars Vilks, who has drawn caricatures of the Prophet Muhammad, is understood to have been present at the debate, as well as the French ambassador, Francois Zimeray.
