At least 11 people were killed after a gunman opened fire at Pittsburgh's Tree of Life synagogue. According to the report, the gunman yelled "All these Jews need to die".

The gunman has been preliminarily identified as 46-year-old Robert Bowers. The shooting reportedly happened during a circumcision ceremony and over 12 people were shot. 80 people were in the Synagogue during the shooting. Bauer also shot three police officers.

Tree of Life Congregation was founded more than 150 years ago and joined with the newer Or L’Simcha Congregation about 5 years ago to form the Tree of Life*Or L’Simcha Synagogue affiliated with the Conservative Movement.

The attack was condemned by President Trump, who tweeted that he is "Watching the events unfolding in Pittsburgh, Pennsylvania. Law enforcement on the scene. People in the Squirrel Hill area should remain sheltered. Looks like multiple fatalities. Beware of active shooter. God Bless All!"

Trump later said during a rally on Indianapolis that "There must be no tolerance for anti-Semitism in America or for any form of religious or racial hatred or prejudice"

"We are praying for the families of the victims and our hearts go out to the wounded law enforcement officers in Pittsburgh."

"I was heartbroken and appalled by the murderous attack on a Pittsburgh synagogue today," said Prime Minister Netanyahu.

"The entire people of Israel grieve with the families of the dead. We stand together with the Jewish community of Pittsburgh. We stand together with the American people in the face of this horrendous antisemitic brutality and we all pray for the speedy recovery of the wounded."

Diaspora Affairs Minister Naftali Bennett condemned Saturday's grisly shooting, tweeting that "The State of Israel and the Israeli government received with shock and pain the reports of the terrible attack on the Jewish community in Pittsburgh. We anxiously follow the reports and pray that the event will end soon."

"At the same time, I have now instructed the Ministry of Diaspora Affairs to prepare to assist the community in every possible way. Our hearts are with the families of those killed and injured. May the memory of the murdered be blessed. "

Israeli officials say that Prime Minister Netanyahu is closely following the situation in Pittsburgh. The shooting was also condemned by Jewish Agency Chairman Isaac Herzog.

"A terrible massacre during the Shabbat service at the Etz Hayyim Synagogue in Pittsburgh," said Herzog. "We at the Jewish Agency are sore and distressed by the disaster of the warm Jewish community of Pittsburgh. The Jewish Agency is ready to assist in any way to the Jewish community in Pittsburgh and expresses its deep sorrow over the loss of life and the injury to the wounded."
