A prison inmate in northern France has seriously wounded two guards in a knife attack, in what French ministers have described as a "terrorist incident", reports the BBC.
Michaël Chiolo was later detained in a police raid carried out on Tuesday evening.
He and his female partner, who was visiting him, had been barricaded in the family-visiting area of a Normandy high-security prison since the morning.
Both were shot by police, and she is now said to have died of her wounds.
One of the guards suffered a serious abdominal wound, while the second was slashed on the face and back, reports say.
Chiolo shouted "Allahu Akhbar" (God is Greatest) during his attack, reports said.
"It was truly a murder attempt. There was blood everywhere. The family-visiting unit was a battle scene," a prison staff representative told AFP news agency.
It is thought the ceramic knife Chiolo used might have been smuggled into the prison by his partner, Justice Minister Nicole Belloubet said.
