The border city of Reynosa is Mexico's new front on the war on drugs.

A growing turf battle between drug cartels has terrorised locals and the situation has deteriorated to the extent that residents are afraid to go outside, even during the day.

Journalists are also fearing for their lives after some reporters were targeted by gangs.

The US-based Committee to Protect Journalists is now calling on the Mexican government to investigate a series of kidnappings of reporters covering the drug war in the area.
