Burundian time-bomb

WHEN a Hutu politician says it is time to “pulverise and exterminate” rebels who are “good only for dying”, outsiders should sit up. When he talks of spraying “cockroaches” or urges people to “start work”, it is hard to miss the old codewords for massacring Tutsis. When the politician is not some obscure backbencher but the president of the Burundian Senate, the world should be alarmed.
