Several legal experts have told BBC Verify that the second strike on an alleged Venezuelan drug boat by the US military was probably illegal, and would likely be considered an extrajudicial killing under international law.
On Monday, the Trump administration confirmed that a follow-up strike on the boat - which has been criticised as a "double tap" - was ordered by US Navy Admiral Frank Bradley with the overall operation having been authorised by War Secretary Pete Hegseth.
Nine people died in the first strike on the vessel and two survivors were left clinging to the burning wreckage when it was struck again, killing them, according to the Washington Post. A US official has said four missiles were used in the operation.
The Trump administration has not denied there were survivors and has insisted the strikes on 2 September were "in accordance with the law of armed conflict".
President Donald Trump posted what appeared to be footage of the first strike on 2 September, on his Truth Social platform. The 29-second clip purports to show the first attack from two different angles although the images are not clear.
