Journalists killed in Mexico's Veracruz

Journalists in Mexico are marking World Press Freedom Day by mourning the deaths of three colleagues killed in Veracruz.

Their deaths highlight the risk many reporters take on a daily basis to do their job. Reporters Without Borders says worldwide, 67 journalists were killed in 2011.

The latest killings in Mexico came less than a week after the murder of an investigative reporter in Veracruz, from where Al Jazeera's Franc Contreras reports.
