At least nine US citizens, including six children, have been killed in a violent attack by suspected drug cartel gunmen in northern Mexico.
The victims are members of the LeBaron family, linked to a breakaway Mormon community which settled in Mexico several decades ago.
The victims, who also include three women, were travelling in a convoy.
Mexico’s security minister said the group could have been targeted accidentally through mistaken identity.
Family members, who have spoken to the New York Times newspaper, said two of the children killed were less than a year old.
In a Tuesday-morning tweet President Donald Trump described the group as “a wonderful family and friends” who “got caught between ‘two vicious cartels'”.
In a series of posts, he signalled that the US “stands ready” to offer support to combat the problem.
