WARNING - VIDEO CONTAINS GRAPHIC CONTENT
The site of a daring daylight attack in Mexico's northern city of Monterrey.
According to local media, armed men approached a house here at about midday on Tuesday and opened fire on drivers allegedly operating an informal taxi hub in the area.
Six drivers and one pedestrian were killed.
Not far from the scene, a woman was also found dead.
Authorities are investigating whether the killings were related.
There was no clear motive behind the attack.
Just a few years ago, the manufacturing town with a population of four million 140 miles from the Texas border was considered a model for developing economies.
Now Monterrey is a symbol of Mexico's ultra-violent drug war, overrun with gangland killings and ever-increasing lawlessness.
55,000 people in Mexico have been killed in drug-related violence over the past six years.
