A Rwandan politician who stirred up controversy with comments on the genocide recently has been attacked by a group of men at a government office.

About 10 men set upon Victoire Ingabire and her driver as they waited for papers to register their party for next year's election.

She escaped unharmed but her driver was said to have serious injuries.

Ms Ingabire, a Hutu, was criticised last month for highlighting crimes against Hutus during the 1994 genocide.
