Trump Calls for 'War' on Cartels as 6 Children Among 9 US Mormons Murdered in Mexico

Mexico City: US President Donald Trump offered Tuesday to help Mexico "wage war" on its cartels after three women and six children from an American Mormon community were murdered in an area notorious for drug traffickers.

Gunmen ambushed the members of the LeBaron family -- a large clan of Mormons who emigrated to Mexico in the late 19th century -- as they traveled on a rural road Monday in a lawless region between the border states of Sonora and Chihuahua.

Mexican officials said six children were wounded and another girl missing after the attack, which left the family's three cars riddled with bullets and utterly charred, as seen in images posted on social media by devastated relatives.

"If Mexico needs or requests help in cleaning out these monsters, the United States stands ready, willing & able to get involved and do the job quickly and effectively," Trump wrote in a tweet.

He praised Mexican President Andres Manuel Lopez Obrador for prioritizing the fight against drug trafficking, but said "the cartels have become so large and powerful that you sometimes need an army to defeat an army!"

"This is the time for Mexico, with the help of the United States, to wage WAR on the drug cartels and wipe them off the face of the earth. We merely await a call from your great new president!" Lopez Obrador said he would call Trump and accept "all necessary cooperation."

But the left-wing populist, who has declared an end to Mexico's "drug wars," said he was not looking for a new one.

"We don't agree (with Trump) on that. We respect those who think that way, but it goes against our convictions. War is the worst thing there is," he told a news conference.

"War is synonymous with irrationality."

Shocked, outraged members of the LeBaron family took to social media to call for people's prayers and condemn the lawless violence gripping much of the border region.

The victims "were ambushed by the Mexican cartels; shot, burned, and murdered in cold blood. These were innocent civilians," said one.

"It was a massacre," Julian LeBaron, an activist who has denounced criminal groups in the area, told Mexican radio network Formula.
