It's estimated that more than 200,000 people in Mexico have either been killed or disappeared since the country's government, then headed by former Mexican President Felipe Calderón, declared war on organised crime in December 2006.

The Mexican security minister stated Tuesday that nine people, three women and six children, have been killed in an ambush on a Mormon family in Northern Mexico.

The official further stated that the murdered people travelling in a convoy, could have been confused with criminal groups fighting for control in the region.

US President Donald Trump has turned to Twitter amid the ongoing investigation to lambast those responsible for the crime and to propose US support for Mexico.

....monsters, the United States stands ready, willing & able to get involved and do the job quickly and effectively. The great new President of Mexico has made this a big issue, but the cartels have become so large and powerful that you sometimes need an army to defeat an army! — Donald J. Trump (@realDonaldTrump) 5 ноября 2019 г.

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! — Donald J. Trump (@realDonaldTrump) 5 ноября 2019 г.

Commenting on Trump's proposal, Mexican President Lopez Obrador said that his country was ready to work with the FBI in the war against drug cartels.

Earlier in the day, media said the Mexican authorities had deployed national police and military forces to the northern state of Sonora bordering the US following reports of at least seven US citizens, including children having been killed.

The reports of the massacre emerged late on Monday as Lafe Langford Jr, a member of the Church of Jesus Christ of Latter-day Saints, which has a major presence in the region, posted a statement on Facebook, saying that a mother and four of her children had been killed by drug cartels.

According to Mr Lafe Langford Jr, Rhonita Miller and her 4 children were shot up and burned to death in a vehicle.

Mr Lafe Langford Jr has been updating the information as the situation develops, saying that two other women who were previously missing - Christina Langford and Dawna Langford and their children have also been killed.
