In Uganda, naked photos of the musician Desire Luzinda have gone viral on social media networks, and have been published in newspapers.

Her ex-boyfriend is alleged to have posted them, saying he wanted to teach her a lesson.

Now she is in hiding as the country's minister for ethics has called for her arrest.
