PARIS-French police have detained seven people suspected of plotting a terror attack after an eight-month investigation, French Interior Minister Bernard Cazeneuve said Monday.

The seven individuals were arrested in Marseille on the Mediterranean coast and in Strasbourg on the border with Germany, Mr. Cazeneuve said in a media conference. The suspects are French, Moroccan and Afghan nationals aged between 29 and 37, he said.

"Yesterday, the department of interior security foiled a terrorist action that was being planned for a long time on our soil," Mr. Cazeneuve said.

The suspects had links with five other people detained on June 14 ahead of the Euro 2016 soccer tournament held in France, he added.

French authorities have given security forces sweeping powers to hunt down potential terrorists after a series of attacks that have killed more than 200 people over the last 12 months.

As many as 418 people with links to terrorist networks have been detained since the start of the year, Mr. Cazeneuve said.
