A UNITED States national was this week arrested at Harare airport when some 80 rounds of ammunition were found in his luggage. The Daily News reported on Wednesday that airport manager Robert Dombodzvuku said the unnamed man was arrested on Monday, as he was about to board a domestic flight from Harare to the second largest city of Bulawayo in the western Matabeleland province. Three other Americans — John Lamonte Dixon, Gary George Blanchard and Joseph Wendell Pettijohn — are currently in detention in Zimbabwe facing terrorism and espionage charges.
