BERLIN -- German authorities say they've searched the homes of three former SS men believed to have taken part in a World War II massacre in northern France.

Prosecutor Andreas Brendel told The Associated Press on Friday that the homes of the three men, all around 90 years old, were raided this week in Saxony and Lower Saxony. Authorities confiscated documents, photos and other possible evidence.

The three are believed to have been members of the 12th SS Panzer Division "Hitler Youth," which was responsible for the massacre of 86 men in Ascq, France, in 1944.

Brendel says all three men, whose names he would not release, are believed to have been present for the massacre but deny that they were.

The investigation is ongoing and no charges have been filed.
