'Journalism Under Attack in Mexico'

Over 38 journalists in Mexico have been killed or disappeared:

Felipe Calderon, Mexico’s president, has warned that the country’s drug war is entering a new phase as gangs increasingly target journalists who cover the violence.

His warning follows the release of four journalists kidnapped by a cartel in northern Mexico last week.

Their release is a rare fate for most abducted journalists in the country, where many have been killed by drug cartels and others remain missing.
