The awkward camera angle is meant to hide the fact that the owner of the phone is filming, but there is no mistaking the outlines of the heavy cargo being deposited on the dock in the Yemeni port of Aden last week.
The distinctive shape of the US-made Oshkosh armored vehicle stands out in the early morning darkness, a piece of military hardware that is currently at the heart of a standoff between some American lawmakers and President Donald Trump's administration.
Aden is controlled by the Saudi-led coalition in Yemen, whose main partners are continuing to ship American-made weapons into the country despite bipartisan outrage in Congress over the way the US is backing Riyadh in this bloody and bitter conflict.
This footage showing the unloading of a variety of US-made arms -- which was filmed illicitly at the offloading site, then obtained and verified by CNN -- is itself contentious. Multiple witnesses told CNN that Yemeni authorities, backed by the Saudi-led coalition, have been arresting and questioning those they suspect of leaking it to the media.
Using whistleblower accounts and port documents CNN has identified the ship which offloaded the US weaponry in Aden last week as the Saudi-registered Bahri Hofuf. Looking at tracking data, the vessel's last recorded location was in the Saudi port of Jeddah on September 17, before it sailed to Port Sudan, arriving the following day.
After this, the boat's tracking system was switched off, before it appeared again under the cover of darkness in Aden on October 29.
Secrecy surrounds the flow of weaponry to Yemen's conflict that as of October 31 has killed more than 100,000 people since 2015, according to the Armed Conflict Location & Event Data Project.
The fighting has divided the country's north from south. Iranian-backed Houthis rebels control the capital of Sanaa, while the US-supported, Saudi-led anti-Houthi forces hold Aden. Infighting in the south this summer -- between Saudi-supported forces of the internationally recognized government and UAE-backed separatists -- further splintered territorial control, threatening to plunge the entire country into a protracted and multi-sided war.
A peace deal between government forces and the separatists was signed on Tuesday in the Saudi capital of Riyadh. It aims to end the power struggle around Aden and defer the issue of whether the south will secede until after the battle against the Houthi-controlled north has been won.
