PARIS - A fifth person wounded in the attack that targeted a Christmas market in Strasbourg, east France on Tuesday, succumbed to his injuries, the Paris prosecutor's office confirmed on Sunday evening.

The office said that the victim was of Polish nationality. There are still eleven wounded, some of whom are in serious condition.

On Tuesday evening, a man armed with a firearm and a knife, opened fire several times and stabbed people in Place Kleber and the Grand'Rue, one of the French city's main shopping streets where Christmas market is held every year.

The shooter, identified as Cherif Chekatt, has been killed, on Thursday evening, ending two-day massive manhunt in which 720 security forces had been involved.

Seven people were put in police custody in connection with the gunman as French investigators were working to determine whether he acted alone or with accomplices, Paris prosecutor Remy Heitz said earlier on Friday.
