KDKA has received a tentative identification of the man, but is withholding it until it can be confirmed.

The man reportedly walked through the building indiscriminately shooting people, and said "all Jews must die," according to KDKA's live report.

Saturday mornings are when Shabbat is observed in the Jewish faith and is typically a busy time at synagogues.

Responding officers arrived on the scene when the gunman opened fire, sending officers behind their vehicles for cover, KDKA reports.

Carnegie Mellon University, which is near the scene, has also been placed on lockdown.

The tree-lined residential neighborhood of Squirrel Hill, about 10 minutes from downtown Pittsburgh, has a heavily Jewish population. The congregation's president declined to comment.

KDKA reports about 30 people were inside the synagogue at the time of the shooting.

Police spokesman Chris Togneri said police have no more information at this time because they were still trying to clear the building and determine if any more threats exist.

This story is being updated as more information is released.
