Panama's president says on his Twitter account that authorities have seized a North Korean-flagged ship traveling from Cuba with "undeclared military cargo."

President Ricardo Martinelli offered no details but posted a photo of what appeared to be a green tubular object sitting inside a cargo container or the ship's hold.

Panamanian officials verified the tweet was authentic but did not immediately respond to requests for further details.
