(AP) A North Korean ship carrying weapons system parts buried under sacks of sugar was seized as it tried to cross the Panama Canal on its way from Cuba to its home country, which is under a United Nations arms embargo, Panamanian officials said Tuesday.
The ship appeared to be transporting a radar-control system for a Soviet-era surface-to-air missile system, according to a private defense analysis firm that examined a photograph posted on Twitter by Panamanian President Ricardo Martinelli.
Martinelli said the ship identified as the 14,000-ton Chong Chon Gang was carrying ballistic missiles and other arms, but he provided no specific evidence or details about the cargo. He said on his Twitter account that the arms were "hidden in containers underneath the cargo of sugar."
The photo posted by the president shows a green tube that appears to be a horizontal antenna for the SNR-75 "Fan Song" radar, which used to guide missiles fired by the SA-2 air-defense system found in former Warsaw Pact and Soviet-allied nations, said Neil Ashdown, an analyst for IHS Jane's Intelligence.
Jane's isn't sure where the system in the photo was manufactured but the radar would be useful to North Korea as part of a dense air defense network, Ashdown said.
"It is possible that this could be being sent to North Korea to update its high altitude air-defense capabilities," he said.
The U.N. Security Council imposed sanctions against North Korea after its first nuclear test in 2006 and stepped up sanctions after its second test in 2009 to try to derail the country's rogue nuclear weapons and ballistic missile programs. The second round strengthened an arms embargo, authorized ship searches on the high seas for suspected banned items, and ordered an asset freeze and travel ban on companies and individuals involved in the country's nuclear and conventional weapons programs.
Panamanian authorities believe the ship was returning from Havana on its way to North Korea, Panamanian Public Security Minister Jose Raul Mulino told The Associated Press. Based on unspecified intelligence, authorities suspected it could be carrying contraband and tried to communicate with the crew, who didn't respond.
The 35 North Koreans on the boat were arrested after resisting police efforts to intercept the ship in Panamanian waters on Thursday as it moved toward the canal and take it to the Caribbean port of Manzanillo, Martinelli told private RPC radio station. The captain had a heart attack and also tried to commit suicide during the operation, Martinelli said.
Panamanian officials were finally able to board the ship to begin searching it Monday, pulling out hundreds of sacks of sugar.
The illicit cargo "seems to be a type of missile, of rocket. Next to them there's another container that appears to have a type of control system," said Luis Eduardo Camacho, a spokesman for Martinelli. He said authorities had only searched one of the ship's five container sections, and the inspection of all the cargo will take at least a week.
"This material not being declared and Panama being a neutral country, a country in peace, that doesn't like war, we feel very worried about this war material and we don't know what else will have ... passed through the Panama Canal," Martinelli said.
The governments of North Korea and Cuba made no public comment on the case.
In early July, a top North Korean general, Kim Kyok Sik, visited Cuba and met with his island counterparts. Cuban Communist Party newspaper Granma said he was also received by President Raul Castro, and the two had an "exchange about the historical ties that unite the two nations and the common will to continue strengthening them."
The meetings were held behind closed doors, and there has been no detailed account of their discussions.
"After this incident there should be renewed focus on North Korean-Cuban links," said Hugh Griffiths, an arms trafficking expert at the Stockholm International Peace Research Institute. Griffiths said his institute told the U.N. this year that it had uncovered evidence of a flight from Cuba to North Korea that travelled via central Africa.
"Given the history of North Korea, Cuban military cooperation and now this latest seizure, we find this flight more interesting," he said. "
The Chong Chon Gang has a history of being detained on suspicion of trafficking drugs and ammunition, Griffiths said. Lloyd's List Intelligence said the 34-year-old ship, which is registered to the Pyongyang-based Chongchongang Shipping Company, "has a long history of detentions for safety deficiencies and other undeclared reasons."
Satellite tracking records show it left the Pacific Coast of Russia on April 12 with a stated destination of Havana, then crossed the Pacific and the Panama Canal on its way to the Caribbean. It disappeared from satellite tracking until it showed up again on the Caribbean side of the canal, on Friday, Lloyd's said.
The disappearance from satellite tracking indicates that the crew may have switched off a device that automatically transmits the ship's location after it moved into the Caribbean, Lloyd's said.
Griffiths said the Chong Chon Gang was stopped in 2010 in the Ukraine and was attacked by pirates 400 miles off the coast of Somalia in 2009.
Griffiths' institute has also been interested in the ship because of a 2009 stop it made in Tartus a Syrian port city hosting a Russian naval base.
