Washington  - The United States is doubling, tripling and quadrupling its anti-drug efforts on its border with Mexico even as Mexico has sent 10,000 armed troops into the border city of Juarez to quell drug violence.

Janet Napolitano, secretary of Homeland Security, and other administration officials Monday laid out a huge boost in efforts on the US side of the border to stem traffic in illegal drugs and weapons.

In addition, US justice officials said they were rolling up their sleeves to help Mexico corral the spiralling influence and violence connected to the growing drug cartels.

"The Department of Justice stands ready to take the fight to the Mexican drug cartels," said Deputy Attorney General David Ogden.

Ogden noted that this fight would also be coordinated with homeland security and the US State Department. (dpa)
