Felipe Calderon, Mexico's president, has promised a new security plan for the city of Ciudad Juarez, which is at the centre of the government's battle against drug cartels.

Calderon has also named a new special prosecutor to focus on crimes against journalists. Nearly 90 per cent of murders of reporters go unsolved in Mexico, according to the Committee to Protect Journalists.

Al Jazeera met Luz Soza, a crime reporter in Ciudad Juarez. Here's her story in her own words.
