At least 4 people are dead after a gunman opened fire at a synagogue in Pittsburgh earlier this morning (October 27). According to initial reports from CNN, the shooting at Tree of Life Synagogue left an additional 12 people injured.  

The news organization spoke to Pittsburgh city officials, who said that the as-yet unidentified shooter has surrendered to police and been taken to Mercy Hospital.  

The Chicago Tribune reports that three police officers were shot during the attack in the Jewish neighborhood of Squirrel Hill. 

President Donald Trump tweeted about the incident while residents of the neighborhood were still being told to stay inside.  

"People in Squirrel Hill area should remain sheltered," Trump wrote. "Looks like multiple fatalities. Beware of active shooter. God Bless All!"

Fred Rabner, a member of the Tree of Life congregation who spoke to CNN, said that the "tight-knit community" around the synagogue has been "shaken."

"Everyone is just shaken up and upset," Rabner said. "It's awful, it's just awful."
