Arizona Tribune - Two of four US citizens kidnapped in Mexico found dead

The attorney general's office confirmed that of the four abductees "two of them are dead, one person is injured and the other is alive," Tamaulipas state governor Americo Villarreal told a news conference by telephone.

The US citizens crossed into Matamoros, in Tamaulipas state, on Friday in a white minivan with North Carolina license plates, the US Federal Bureau of Investigation (FBI) said in an earlier statement.

It offered a $50,000 reward for help leading to the return of the unidentified victims and the arrest of the perpetrators.

"Shortly after crossing into Mexico, unidentified gunmen fired upon the passengers in the (minivan). All four Americans were placed in a vehicle and taken from the scene by armed men," the FBI said.

Mexican President Andres Manuel Lopez Obrador said on Monday that the victims were believed to have entered the country to buy medicines and got caught up in a confrontation between criminal groups.

"We're very sorry that this is happening in our country," Lopez Obrador told reporters after the confirmation of the deaths.

"We send our condolences to the families of the victims, to friends, to the people of the United States, to the US government," he added.

A Mexican national was killed in the incident.

Matamoros, located across the US border from Brownsville, Texas, has been beset by violence linked to drug trafficking and other organized crime.

The White House on Monday described the abductions as "unacceptable" and said President Joe Biden's administration was coordinating with Mexican authorities.

"Our thoughts are with the families of these individuals," spokeswoman Karine Jean-Pierre said.

Mexico is plagued by cartel-related bloodshed that has seen more than 340,000 people murdered since the government deployed the military in the war on drugs in 2006.

The US State Department advises against travel to Tamaulipas due to crime and kidnapping.

"Organized crime activity -- including gun battles, murder, armed robbery, carjacking, kidnapping, forced disappearances, extortion, and sexual assault -- is common along the northern border and in Ciudad Victoria," the state capital, according to a US travel advisory.

"Criminal groups target public and private passenger buses, as well as private automobiles traveling through Tamaulipas, often taking passengers and demanding ransom payments," it warned.

Despite the risks, Matamoros, located on the banks of the Rio Grande river separating the two countries, is a major stopping point for migrants heading for the United States.
