France attack: Wife of suspect Yassin Salhi
Police in France are questioning a number of people after a suspected Islamist attack on a chemicals plant in the south east of the country, in which a man was decapitated.
The French interior minister Bernard Cazeneuve said a 35-year-old suspect arrested at the scene, Yassin Salhi, had been monitored by police for two years from 2006 but did not have a criminal record.
His wife is among those detained. Speaking earlier from her home, she told French radio station Europe 1 that she was shocked at the news of her husband's arrest.
"My sister-in-law said 'switch on the TV, the news is on' and she's crying. My heart feels like it's going to stop. I don't understand anything. On the news it said a 'terrorist act' but it's not possible," she said.
