(CNN) -- The massacre of 11 people at a synagogue in Pittsburgh was felt around the nation and the globe.
Leaders from across the world issued statements of condolences.
Here are some of their comments:
Israeli Prime Minister Benjamin Netanyahu issued a video statement, posted to Twitter.
"The entire people of Israel grieve with the families of the dead," he said. "We stand together with the Jewish community of Pittsburgh. We stand together with the American people in the face of this horrendous anti-Semitic brutality."
Canadian Prime Minister Justin Trudeau said the hearts of his nation's people are with the Jewish community.
"May the families of those murdered be comforted, and may the injured recover quickly and fully," he wrote on Twitter.
Angela Merkel, chancellor of Germany, said the people killed and wounded were victims of "blind anti-Semitic hate."
"My sympathies are for the families; I wish for strength + recovery for the victims. We all must stand resolutely against anti-Semitism -- everywhere," she said, according to spokesman Steffen Seibert, who tweeted her comments in German.
In a statement, UN Secretary-General Antonio Guterres called anti-Semitism "a menace to democratic values and peace."
"The Secretary-General calls for a united front -- bringing together authorities at all levels, civil society, religious and community leaders and the public at large -- to roll back the forces of racism, anti-Semitism, Islamophobia and other forms of hatred, bigotry, discrimination and xenophobia gaining strength in many parts of the world," he said.
First lady Melania Trump said the violence needs to stop and the people of the United States need to unite through God.
"My heart breaks over the news out of #Pittsburgh," she wrote on Twitter.
Ivanka Trump, one of the President's daughters and a close adviser, said the United States' people supports Jews.
"America is stronger than the acts of a depraved bigot and anti-semite," she tweeted. "All good Americans stand with the Jewish people to oppose acts of terror and share the horror, disgust & outrage over the massacre in Pittsburgh. We must unite against hated & evil. God bless those affected
Outgoing US Ambassador to the United Nations Nikki Haley also said her heart was breaking.
"An attack on the most sacred of places is the cruelest and most cowardly act a person can do," she tweeted. "There is and will never be any tolerance for hate."
