Obama outraged by consulate killings in Mexico (AFP)

CIUDAD JUAREZ, Mexico (AFP) – .

Suspected drug gang "hit teams" killed two Americans and a Mexican linked to a US consulate in coordinated shootings that marked an ominous turn in Mexico's drug war..

US President Barack Obama said he was "outraged" by the latest killings in the notorious border city Ciudad Juarez on Saturday night..

The Chihuahua state government identified the victims as US consular worker Lesley Enriquez, her American husband Arthur Redelfs and Mexican national Jorge Alberto Salcido Ceniceros, husband of another consulate employee in the city known as Mexico's crime capital..

The slain couple had been traveling in broad daylight in a car with their infant daughter in the back seat. The baby survived unharmed, a US official said on condition of anonymity..

Mexican and US authorities said "The Aztecas," a gang linked to the powerful Juarez drug cartel, may have been behind the drive-by killings..

No motive was suggested, but several prominent drug kingpins have been recently extradited by Mexico to the United States to stand trial..

Jesus Vicente Zambada-Niebla, son of Sinaloa Cartel chief Ismael "el Mayo" Zambada-Garcia, appeared last month in a Chicago court on drug trafficking charges..

Miguel Caro Quintero, a brother of another notorious Mexican drug baron, Rafael Caro Quintero, was sentenced in a Colorado court to 17 years in jail..

The US Congress has approved some 1.3 billion dollars for Mexico under a regional plan to fight organized crime..

The victims had all been at the same party on Saturday night, the US official said..

In a second attack, the Mexican employee was following her husband and two children in a separate car, when her husband's vehicle came under fire, killing him and wounding the two children, the official said..

The US State Department authorized US staff in six consulates along the US-Mexican border to send their dependants home for safety..

It also warned US citizens to "delay unnecessary travel" to parts of Durango, Coahuila and Chihuahua states, arguing that "violence in the country has increased.".

The State Department noted that some of the recent clashes resembled small-scale warfare, with drug cartels using automatic weapons and grenades..

Moreover, "drug cartels and associated criminal elements have retaliated violently against individuals who speak out against them or whom they otherwise view as a threat to their organizations," it warned..

Obama said that he was "deeply saddened and outraged by the news of the brutal murders.".

Secretary of State Hillary Clinton offered her "deepest sympathies" to the families of those slain..

"These appalling assaults on members of our own State Department family are, sadly, part of a growing tragedy besetting many communities in Mexico," she said in a statement..

Ciudad Juarez, population 1.3 million, is a major hub for smuggling illegal drugs into the United States. It is directly across the border from El Paso, Texas..

More than 2,600 people were murdered in Ciudad Juarez in 2009 in drug-related violence..

The war between rival drug cartels to control border crossing points, as well as the government's attempt to crack down on the cartels, has left more than 15,000 dead across Mexico over the last three years, according to government figures..

This past weekend, the drug war claimed 31 more victims in several shootings that occurred in and around the famous Mexican resort of Acapulco..

About 1,000 college-age US youngsters are reported to be in Acapulco this week for the traditional spring break.
