The Mexican authorities have 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.
The US State Department said that it’s aware of the situation but has no further comment.
