A strike carried out by US forces on a boat in the Caribbean Sea - which the White House says killed 11 drug traffickers - may have violated international human rights and maritime law, legal experts have told BBC Verify.

President Donald Trump announced on Tuesday that US forces destroyed a vessel which he said had departed from Venezuela. He said the boat was operated by the Tren de Aragua cartel and was carrying drugs bound for the US.

US defence officials have so far declined to offer details on the strike, footage of which Trump shared on Truth Social, including what legal authority they relied upon to justify it.

BBC Verify reached out to a range of experts in international and maritime law, with several saying that US may have acted illegally in attacking the vessel.

The US is not a signatory to United Nations Convention on the Law of the Sea, but the US military's legal advisors have previously said that the US should "act in a manner consistent with its provisions".

Under the convention, countries agree not to interfere with vessels operating in international waters. There are limited exceptions to this which allow a state to seize a ship, such as a "hot pursuit" where a vessel is chased from a country's waters into the high seas.

"Force can be used to stop a boat but generally this should be non-lethal measures," Prof Luke Moffett of Queens University Belfast said.

But he added that the use of aggressive tactics must be "reasonable and necessary in self-defence where there is immediate threat of serious injury or loss of life to enforcement officials", noting that the US moves were likely "unlawful under the law of the sea".

Experts have also questioned whether the killing of the alleged members of the Tren de Aragua cartel could contravene international law on the use of force.

Under Article 2(4) of the UN charter, countries can resort to force when under attack and deploying their military in self-defence.........
