SANAA  - A cargo of weapons originating in Turkey was seized by Yemeni authorities in the port of Aden, the defence ministry Internet website 26sep.net reported. Citing security sources, the report said the arms had been found in boxes used for biscuits, in a container dispatched from Turkey. An investigation has been opened into the discovery of weapons “destined to harm the security and stability” of Yemen, the ministry said, without identifying either the sender or intended recipient of the cargo. The impoverished southern Arabian Peninsula nation is already awash with weapons. It is prey to attacks in the east and south blamed on Qaeda in the peninsula that have become more frequent in the wake of the 2011 popular uprising.
