The most serious incident of this kind involving box cutters was of course the September 11th attack in 2001, which saw four groups of migrants hijack domestic airliners in the United States and crash three into the World Trade Center and Pentagon building, killing nearly 3,000 people and injuring over 6,000.
In March this year a man was shot and killed by police in the Carcassonne area of southern France after killing four people.

The 24-year-old assailant, who did not have a police record, was overpowered by others in the supermarket and has been taken into custody.
According to witnesses, dressed in black, the woman first hit with a utility knife of the visitor of a supermarket, and then the cashier.
Both victims have been taken to hospital. The perpetrator may also be suicidal as she asked the police to kill her during the arrest, saying that she had nothing to lose, the prosecutor added. "We don't yet know if this is a terrorist act, but in any case it was terrifying", he added. The law enforcers have been searching her home, checking whether she had links to Islamic State (IS, formerly ISIS) or other radical groups.
The woman, who carried a physical handicap card, would undergo a psychiatric assessment.
