Obama says U.S. drone strikes killed civilians 'that shouldn't have been'

U.S. President Barack Obama speaks during a conference at Buenos Aires' Town Hall, March 23, 2016. WASHINGTON -- President Barack Obama acknowledged Friday that "civilians were killed that shouldn't have been" in past U.S. drone strikes, but said the administration is now "very cautious" about striking where women or children are present. Obama was asked at a news conference about an increase in the number of people targeted in drone strikes against extremists in Libya, Syria, Somalia and elsewhere. "In the past, there was legitimate criticism that the legal architecture around the use of drone strikes wasn't as precise as it should have been," Obama said. "There's no doubt that civilians were killed that shouldn't have been."
