Authorities in Panama say they have found more explosives aboard a North Korean-flagged ship detained in the Panama Canal for carrying undeclared arms from Cuba, AP reported. Anti-drug prosecutor Javier Caraballo said Saturday that inspectors found a kind of "anti-tank RPG (rocket-propelled grenade)" explosive when they opened one of five wooden boxes on the Chong Chon Gang. He said the other boxes were not opened because of security fears. The discovery comes just over a week after authorities said explosive-sniffing dogs had found another batch of ammunition for grenade launchers and other unidentified types of munitions.
