UK's top law officer outlines legal basis for drone killings

Britain's top law enforcement official says it is legal to kill militants overseas if they pose an immediate or otherwise unstoppable threat. Attorney General Jeremy Wright is using a speech Wednesday to lay out the legal basis for the use of lethal force. Excerpts were released in advance. A Royal Air Force drone strike in Syria killed three Islamic State group fighters in 2015, including two Britons. It was the first such strike acknowledged by the British government.
