    A United Nations special    (1)    recently called for a ban on the production and use of lethal autonomous robots, also known as LARs. Critics say these "killer robots" may one day choose and strike targets independently, without human    (2)    .

    UN official Christof Heyns says the lack of human commanders raises many moral and    (3)    questions about LARs. He spoke last month at a meeting of the UN Human Rights Council in Geneva, Switzerland.

    "War without reflection is mechanical slaughter, in the same way that the taking of any human life    (4)    - as a minimum - some deliberation, a decision to allow machines to be deployed to kill human beings worldwide. Whatever weapons they use, deserves a collective pause."

    Mr Heyns says "killer robots" should not have the power of life and death over human beings. He    (5)    with people who say the robots could help reduce the possibility of human error, or accidental death.

    "In some cases, people also make mistakes with their act of fear, or may even be driven to act out of revenge or cruelty. Yet at the same time, humans may in some cases, unlike robots, act out of    (6)    ."

    President Obama called the use of drones "effective", but he noted that the new technology raises what he called profound questions.

    "As our fight enters a new phase, America's legitimate claim of self-defense cannot be the end of the discussion. To say a military tactic is legal, or even effective, is not to say it is wise or moral in every instance, for    (10)    ."

    Shortly after his speech, the Pakistani Taliban reported that its number 2 commander was killed in a suspected American drone strike.
