Robert Lewis Dear, a 57-year-old from North Carolina, has been named as the gunman behind a massacre at a Colorado Planned Parenthood clinic in which three people died and nine were injured.In a statement Friday night, Planned Parenthood said: \u0022We share the concerns of many Americans that extremists are creating a poisonous environment that feeds domestic terrorism in this country.\u0022Barack Obama said on Saturday the US had “to do something about the easy accessibility of weapons of war on our streets to people who have no business wielding them”.“Period,” the president added, in a statement released by the White House. “Enough is enough.”U.S. Sen. Bernie Sanders issued this statement today: “While we still do not know the shooter’s motive, what is clear is that Planned Parenthood has been the subject of vicious and unsubstantiated statements attacking an organization that provides critical health care for millions\u0026nbsp;of Americans. I strongly support Planned Parenthood and the work it is doing and hope people realize that bitter rhetoric can have unintended consequences.”\u0026nbsp;Tweets about #ColoradoSprings #PlannedParenthoodUpdate (7:30 PM ET): Gunman surrenders to policeThe Guardian reports:A gunman has surrendered after an hours-long standoff inside a Planned Parenthood clinic in Colorado Springs that left 11 people injured, including five officers, police said on Friday.Colorado Springs mayor John Suthers confirmed the arrest of the gunman, whose condition was not clear.
