Reinforced Mexican anti-drug units began stopping and searching cars at roadblocks along the U.S. border in an operation expected to last several weeks, officials reported. “An operation was established along all of the border,” said Jose Silva Arroyo of the federal judicial police in Matamoros, across the border from Brownsville, Tex. Judicial police, the army and federal highway police, backed by planes and helicopters, are taking part, according to anti-narcotics officials. The operation extends along much of the northern border and south close to the city of Chihuahua, a police commander said.
