At first glance they look like any other bullet. A 540mm sliver of brass built for one purpose - to kill humans. But bullets tell a story. The markings around the circular primer at the base of the casings reveal they were manufactured in Iran - a country supposedly under an international arms embargo.
Since 2010, these cartridges have flooded into west and central Africa. Some are bought on the black market, peddled by soldiers looking to make some cash on the side. Others have been illegally smuggled to countries known for gross human rights abuses.
Iranian-made bullets have appeared in the hands of both rebel and government forces in the Ivory Coast, a country supposedly banned from importing new weaponry.
Virtually every major commodity is regulated by international agreement. Yet there are no global conventions or treaties prohibiting the arms trade, valued at US$411 billion ($512 billion) in 2010.
Even when arms embargoes are in place, dealers find loopholes to smuggle their way into supposedly closed markets. Only 52 countries have laws regulating arms brokers - and fewer than half of those have criminal or monetary penalties for illegal brokering.
