The suspected mastermind of last week's Paris attacks was killed in the police raid of an apartment north of the capital, French officials said on Thursday.

Abdelhamid Abaaoud, a 28-year-old Belgian militant who had boasted of mounting attacks in Europe for the Islamic State, was accused of orchestrating last Friday's coordinated bombings and shootings in the French capital, which killed 129 people.

"It was his body we discovered in the building, riddled with bullets," a statement from the Paris prosecutor said, a day after the pre-dawn raid. The prosecutor later added that it was unclear whether Abaaoud had detonated a suicide belt.
