The ministry said Thursday that the two men, aged 21 and 22, were charged on Tuesday by an anti-terrorist judge and have been jailed.
They were initially arrested Saturday in the Seine-et-Marne region, near Paris. A security official speaking on condition of anonymity said that police searches on property linked to the suspects found knives, a detonator and Islamic State group propaganda material.
Authorities did not provide any further details about the planned attack.
