At least 2 killed, 7 wounded in explosion in western Mexican state of Michoacan

An explosion outside a local police station in the western Mexican state of Michoacan Saturday killed at least two people and wounded seven, local and federal security officials said. The explosion came as the federal government has stepped up security activities in the state, sending in additional troops after two recent high-profile assassinations. Hector Zepeda, commander of the Coahuayana community police, said Saturday the blast killed two of his police officers and that civilians were among the wounded.
