Verdun

Two leaders mark the 300-day 1916 offensive in north-east France that claimed more than 300,000 lives in one of the war's bloodiest battles.

Front National said Black M, due to perform at the late-May remembrance ceremony of WWI battle, has recorded songs calling France a country of infidels.

About 30 million shells were fired in the WW1 battle in NE France which, over 300 days, left an estimated 800,000 soldiers dead, wounded or missing.
