A German citizen and a Turkish national have been arrested in Germany on terrorism charges, authorities said.

The German citizen is a 27-year-old man of Afghan descent who allegedly received terrorist training at a militant camp along the Afghanistan-Pakistan border, while the Turkish man, also 27, had attempted to reach the same camp but was detained by Pakistani authorities, The Washington Post reported Saturday.

German prosecutors said the two men shared a bank account with three other men arrested last year in connection with an alleged plot by the Islamic Jihad Union to bomb U.S. targets in Germany. Authorities this month charged those suspects with hatching a plan to use homemade explosives to bomb U.S. military bases and a dance club in Giessen.

Both of the men arrested Thursday were charged with membership in a terrorist group, the Post said.
