The AP reports:

The governor of Pakistan's powerful Punjab province was shot dead in the capital Tuesday by one of his own guards, who later told interrogators afterward that he was angry about the politician's stance against the country's blasphemy law, officials said. The killing of Salman Taseer was the most high-profile assassination of a political figure in Pakistan since former Prime Minister Benazir Bhutto was assassinated in December 2007, and it rattled a country already dealing with crises ranging from a potential collapse of the government to a virulent Islamist insurgency.
