WHAT WE KNOW – AT 5:56 P.M. ET:  The Pittsburgh shootings dominated today's news.  Here is what we know so far.  From Fox:

A gunman opened fire in a Pittsburgh synagogue on Saturday morning, killing 11 people and injuring six others, including four police officers, before being taken into custody, authorities said.

Pittsburgh Public Safety Director Wendell Hissrich said police were dispatched to Tree of Life Synagogue at 9:55 a.m. after receiving calls that there was an active-shooter situation at the scene, in the city's predominantly Jewish Squirrel Hill neighborhood.

In all, he confirmed, 11 people died -- none of them children. As for the injury tally, he said it did not include the shooter, who was taken to the hospital after being taken into custody.

Law enforcement officials identified the suspect in the shooting as Robert Bowers, 48.

University of Pittsburgh Medical Center officials said a 61-year-old woman was among the injured. Her injuries were described as “extremity soft tissue injuries that required cleaning in the operating room.” She is said to be in good condition and recovering.

Another victim was ID'd as a 70-year-old male with gunshot wounds to his torso “involving major organs in his abdomen.” He was undergoing his second operation and in critical condition, hospital officials said.

Police Chief Scott Schubert said that two police officers were hit during initial contact with the shooter and that two SWAT team members were also struck “during an engagement inside the building.” He confirmed that all four law enforcement officials are in stable condition.

COMMENT:  We know almost nothing about the alleged shooter at this hour, except that he has posted anti-Semitic messages on social media.  We don't know if he has a family, or is politically active.  he is believed to have acted alone.
