As U.S. pledges help, Mexico steps up drug busts

By Catherine Bremer

TAMPICO, Mexico (Reuters) - The Mexican army convoy rolled off a Hercules plane in the middle of the night, purred through this sweltering port city's dingy back streets and swooped on traffickers unloading cocaine in a warehouse.

Shipped to Mexico hours before in a container labeled "bread flour", the 11.7 tons seized last week was Mexico's biggest-ever cocaine bust and led to the arrest of a string of police and customs officers thought to be in on the deal.

It capped a flurry of high-profile seizures this year, a triumph that officials put down to better intelligence and more anonymous tip-offs from a public sick of drug violence.

The U.S. government is delighted by the latest raids in northeastern Mexico, controlled by the entrenched Gulf cartel. and plans to give $1.5 billion to help Mexico's anti-drugs war.

President Felipe Calderon deployed 25,000 troops last December to back up police in fighting the cartels, whose tit-for-tat murders have spiraled out of control.

Welcome as the cash will be, alongside the $7 billion Calderon is putting in, Mexican officials say the leap in drug seizures and arrests shows they are already making progress.

What they really need from the United States, they say, is a crackdown on its huge market for illicit drugs and on the arms dealers who keep Mexico's cartels flush with everything from handguns to rocket-propelled grenades.

"If there are no weapons, there's no violence. These arms aren't from Mexico, they're from the other side," Gen. Javier del Real Magallanes, head of the army drug operation for northeastern Mexico, told Reuters in an interview this week.
