Emergency services arrived at the scene at about 10:00 local time (14:00 GMT), during a service.
Two officers – among the first responders – were injured in an initial confrontation with the shooter.
A further two SWAT team members were hurt inside the building, clashing with the shooter.
All four are in a stable condition, authorities said.
A 61-year-old woman and a 70-year-old man are also currently being treated. The man had gunshot wounds to the torso and is in a critical condition.
The gunman is now in custody after surrendering to the authorities.
The crime scene was “horrific”, Pittsburgh’s Public Safety Director Wendell Hissrich told reporters. “One of the worst I’ve seen, and I’ve [worked] on some plane crashes. It’s very bad,” he added.
What is the synagogue?
The Tree of Life was set up more than 150 years ago, its website says.
It merged with nearby Or L’Simcha congregation about five years ago, to form the Tree of Life – Or L’Simcha Congregation.
The synagogue is in Pittsburgh’s east-end Squirrel Hill area, which has a large Jewish community dating back to the 1920s.
The shooter entered the building during a baby naming ceremony.
The Jewish Federation of Greater Pittsburgh’s president Jeff Finkelstein told reporters up to 50 or 60 people regularly worshipped there on Saturday morning.
According to the calendar on its website, Shabbat morning services were scheduled between 09:45 and 12:00.
A Shabbat training programme for children “in kindergarten through 7th grade” was set to run from 10:15 to 11:45, at which attendees learn prayers, take part in the service and study the Torah.

What do we know about the gunman?
The suspect has been named as Robert Bowers.
FBI special agent Bob Jones said he did not know if Mr Bowers was known to authorities prior to events on Saturday.
Mr Bowers has posted anti-Semitic content on social network Gab under the username “onedingo”.
His bio on his account – now suspended – read: “Jews are the children of Satan”.
On Saturday morning, he attacked refugee aid group Hebrew Immigrant Aid Society (HIAS) and said he could not “sit by and watch my people get slaughtered”.
“Screw your optics, I’m going in,” he wrote.
In earlier posts, he attacked US President Donald Trump and the Jewish community.
“Trump is a globalist, not a nationalist,” he wrote. “There is no #MAGA as long as there is a kike infestation.”
In another post, he said: “For the record, I did not vote for him [Trump] nor have I owned, worn or even touched a maga hat.”
He also expressed support for the QAnon conspiracy – an unsubstantiated loose far-right fringe theory based on the belief that Mr Trump is organising a secret plan to investigate and arrest famous or politically elite child abusers.
What is Gab?
Gab is a social network site created in August 2016 as an alternative to Twitter.
Founder Andrew Torba told Buzzfeed News he set it up as a response to the “entirely left-leaning Big Social monopoly”.
Critics say it is a space for hate speech and people banned from mainstream social media. It was dubbed “the ultimate filter bubble” in a Wired editorial that attacked the network.
However, Mr Torba stressed the site was not for any particular group or political supporters, and has reiterated this on his Gab page.
The site’s guidelines state its mission is “to put people and free speech first” – although calling for violence, illegal pornography and posting confidential person information about users is prohibited.
In the wake of the shooting, the website released a statement condemning the attack.
“Gab unequivocally disavows and condemns all acts of terrorism and violence,” it read. “This has always been our policy.”
The network says it promptly backed up all the data on the alleged shooter’s account, suspended it, and then contacted the FBI with the information.
