President Barack Obama, no stranger to issuing somber calls for action in the wake of armed tragedy, declared "enough is enough."

Colorado Springs, which was blanketed by snow as the drama unfolded over several hours into the early evening Friday, is also ringed by three military bases and the US Air Force Academy.

Concern for the victims and praise for police and law enforcement personnel quickly descended into pressure on the political front, including for tighter gun laws.

President Barack Obama, no stranger to issuing somber calls for action in the wake of armed tragedy, declared "enough is enough."

Friday's nearly six-hour standoff again put the United States' gun culture in the spotlight and also triggered renewed scrutiny of Planned Parenthood, a nationwide health provider that carries out abortions and has faced violence and threats in the past.

Robert Lewis Dear, 57, a bearded drifter who surrendered to police at the scene, is expected to eventually face state charges of murder and attempted murder.

Dear will appear from a courtroom facility at the El Paso County Jail and the hearing starts at 1:30 pm (2030 GMT) on Monday, when a judge will advise him of his rights.

Colorado Springs Mayor John Suthers told ABC's "This Week" talk show on Sunday that police have yet to disclose what Dear told them under interrogation as to his motive.

But asked if he thought the clinic was specifically targeted, Suthers said: "It certainly appears that way."

NBC News, citing two law enforcement officials, reported that Dear mentioned "no more baby parts" when questioned.

Police named the two civilians killed as Jennifer Markovsky, 35, and Ke'Arre Marcell Stewart, 29.
