New York - Four corporate executives were among seven people accused of buying or selling Cuban cigars and charged with "trading with the enemy", judicial sources said yesterday. The seven, arrested on Wednesday and Thursday and released on bail, face prison terms of up to 10 years and $100,000 in fines for violating the US trade embargo with Cuba. On Wednesday, customs officers arrested the manager and an assistant at a chic Manhattan restaurant and the manager of a men's club where 15,000 Cuban cigars were found.
