In a statement read on state television yesterday, Havana said the "obsolete" weaponry included anti-aircraft missile arrays, nine disassembled missiles and other parts, without mentioning where they were being sent.
"The agreements Cuba has signed in these areas are based on our need to maintain our defensive capacity to protect national sovereignty," the statement said.
Panama yesterday called for UN investigators to inspect a shipment of suspected weapons parts aboard a North Korean-flagged ship as it tried to enter the Panama Canal last week.
Panama said the contraband munitions were hidden under thousands of bags of sugar aboard the North Korean-flagged Chong Chon Gang.
Officials said if the shipment is determined to contain missile components, that could violate a UN ban on most weapons being shipped into or out of North Korea.
