MEXICO CITY, Sept. 10 (Xinhua) -- As many as 25 people were murdered in the past 24 hours in Ciudad Juarez, Mexico's most violent city, a local prosecutor told Xinhua on the phone on Friday.

The deadliest incident was the shooting of six people in the Ampliacion Aeropurto neighborhood on a public street. In two other incidents, killers entered the victims' homes and slew at least four people. There were also 11 incidents that involved the murder of one person.

Ciudad Juarez is Mexico's most violent city due to an ongoing clash between drug smuggling organizations that want to use it as a base to move drugs into the United States.

Mexican President Felipe Calderon has sent troops to police the city as part of a war targeting the smugglers since December 2006.

According to official figures, 28,000 people have died in battles -- mostly between rival drug gangs -- since the campaign began.
