People hold French and Israeli flags as they attend a silent march in Paris to pay tribute to the four victims killed by a gunman in Toulouse. The killings were carried out with the same heavy calibre .45 automatic pistol that was used in two attacks that murdered three soldiers of North African and Caribbean origin in the region last week. In all three incidents the lone gunman arrived and escaped on a dark-coloured high-powered scooter.
