Researchers from Human Rights Watch have called on the US to assess the impact of drone attacks in Yemen, which they say are in "clear violation of the laws of war."
The calls come as Human Rights Watch and Amnesty International released two reports investigating who died as a result of the attacks in Yemen and Pakistan.
The US says it is taking all possible precautions during targeted killings, but it has unlawfully killed civilians and struck questionable military targets in Yemen.
Yemenis told us that these strikes make them fear the US as much as they fear al-Qaeda.
The US should investigate attacks that kill civilians and hold those responsible for violations to account. It's long past time for the US to assess the legality of its targeted killings, as well as the broader impact of these strikes on civilians.
