A well known Ugandan gay rights activist David Kato has been found beaten to death in Kampala. Mr Kato's picture had been published by an anti-gay newspaper and he was the subject of a hate campaign.

Ugandan police say that the killing had nothing to do with Mr Kato's homosexuality, but tonight US President Barack Obama demanded an investigation, and human rights groups want an independent inquiry.

Liz MacKean reports on Mr Kato's life, death and the treatment of gay people in Uganda.
