This is horrific.

At least three moms and their six children were killed by Mexican drug cartels while they were traveling between Sonora and Chihuahua:

According to reports, they were traveling to a wedding when the ambush occurred:

One theory is that it was a case of mistaken identity:

Some of the family members survived. From Slate:

Nine members of a Mormon community of dual U.S.-Mexican citizens were killed in northern Mexico Monday in a what appears to be a vicious drug cartel attack. Mexico’s minister for public security confirmed Tuesday that three women and six children were killed in broad daylight as they drove on a highway in the border state of Sonora, an area contested by organized-crime groups. One vehicle reportedly stopped because of a flat tire and assailants attacked the stranded car, killing the driver and four children, including 6-month-old twins. The attackers then set the car on fire.

Two other cars were attacked nearby, killing two women and two children. A member of the family described a scene where a child was gunned down while running away. There are believed to be at least eight survivors, including as many as seven children who reportedly escaped. Some of the escaped children were seriously wounded, including a 9-month-old who was shot in the chest and a 4-year-old shot in the back. One thirteen-year-old reportedly walked 14 miles to the family’s home to get help after hiding his wounded siblings in the brush.

Sonora Gov. Claudia Pavlovich Arellano writes:

“As a mother I feel courage, repudiation and deep pain for the cowards made in the mountains between Sonora and Chihuahua. I don’t know what kind of monsters dare to hurt women and children. As Governor all my collaboration so that it does not go unpunished and those responsible pay.”

President Donald Trump tweeted that the U.S. was ready to provide military assistance if asked:

“. . .the cartels have become so large and powerful that you sometimes need an army to defeat an army!”

And, “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”:

Over to you, Congress:
