Burkina Faso's President Compaore: 'What I'm doing is legal'

Tens of thousands of people have protested in Burkina Faso's capital, Ouagadougou, against moves to extend the president's 27-year rule.

Security forces fired tear gas to disperse protesters who hurled stones and burnt tyres, news agencies report.

In an exclusive interview President Blaise Compaore told BBC Afrique's Liliane Nyatcha that he is acting in the best interests of the country.
