It was mid-morning on a continent otherwise focused on a taxi strike and an EU summit. A 35-year-old resident of the Lyon area was taken into custody over the killing of a subcontractor to US-owned Air Products, a supplier of gas and chemicals. One person was decapitated, several injured, three others taken into custody. Meanwhile, only 99 days after the Bardo museum massacre, Tunisia experienced its bloodiest attack in recent history – this time at a holiday resort, killing at least 37 people.
