Mexico's Senate urged President Felipe Calderon's administration on Tuesday to pressure the United States to find and extradite the U.S. border patrol agent Mexico blames for the fatal shooting of a Mexican on the border with Texas last week.

The killing on September 3 was the second time in two months Mexico complained of one of its nationals being shot over the frontier by U.S. border agents, reports Reuters.

In a statement, the Mexican Senate urged Calderon to start a joint investigation with U.S. authorities over the incident, in order to make an arrest "with the aim of extraditing the agent responsible."

U.S. media reports said the man identified by the Mexican Senate as Guillermo Arevalo Pedraza was shot after rocks were thrown at agents across the border and that the United States had begun an investigation of the incident.

Officials for the U.S. Border Patrol could not immediately be reached for comment.

Laura Rojas, a senator belonging to Calderon's conservative National Action Party, or PAN, said the incident, which took place between Nuevo Laredo in Mexico and Laredo, Texas, was part of a "pattern of repeated violence" against Mexicans.

Meanwhile, Mexico extradited to the United States on Tuesday one of the founders of the brutal Zetas drug cartel who had been linked to the killing of a U.S. customs agent last year.

The Mexican attorney general's office said that former soldier Jesus Rejon, known as Z-7, was handed over to face trial at a federal court in Washington on drug-trafficking charges.

Rejon was captured in July 2011 after being sought in connection with the roadside shooting of two U.S. Immigration and Customs Enforcement agents, one of whom died.

The attorney general's office did not mention the February 2011 killing in its statement on the extradition.
