The government of Zimbabwe has threatened to expel foreign ambassadors who, it believes, are providing support to the opposition Movement for Democratic Change. Zimbabwe's President Robert Mugabe has recently accused the United States, Britain, Sweden and Australia of helping the MDC's political campaign, which he said was aimed at bringing down his government. Those countries have strongly criticized what they describe as police brutality against opposition leaders, some of whom emerged from police detention last week with severe injuries. Zimbabwe's Foreign Minister summoned western ambassadors to deliver a blunt message: support the opposition and you will be thrown out. He said that under the Vienna Convention, embassies were forbidden from interfering in the internal affairs of their host nation. He said President Mugabe's government would not hesitate to expel diplomats who violated the rules.
