A senior Panamanian military officer has charged U.S. military weapons have been smuggled to Panama in violation of the 1977 Canal Treaty signed with the United States.

Lieutenant Col. Aquilino Siero, Panama's chief delegate to the combined Canal Defense Board, blasted the United States Thursday for what he called its "arrogant attitude" toward the treaty and said he would seek an explanation from his U.S. counterpart."For some time now, we have been concerned about U.S. unilateral action and their lack of recognition of the canal treaties," Siero said at a news conference in Colon, some 50 miles west of Panama City.
