A bomb exploded in Mexico City near the security ministry headquarters today, killing one person and injuring two others, the city's police chief said.
Police chief Joel Ortega said a man died in the explosion, which appeared to be caused by a device planted near the ministry building in the city center. A woman and a young man were badly hurt.
"There were two explosions. It was a device that set off two explosions," Ortega told Mexican radio.
President Felipe Calderon has deployed the army in a year-old battle with Mexico's powerful drug cartels. Police have made several busts in the capital and arrested suspected drug gang members found with large arsenals of weapons.
Mexico was also hit last year by a series of nonfatal bomb attacks by a left-wing guerrilla group on oil installations.
