Tel Aviv’s city hall lit up in red, white and blue on Monday, in solidarity with the United States after a gunman killed at least 58 people and injured over 515 more in the worst mass shooting in the country’s history.

The facade of the building displayed an American flag and an Israeli flag, toggling between the two, to show support after the Sunday night shooting in Las Vegas.

The municipality building’s lights are often used to show solidarity with different causes or following terror attacks around the world.

Prime Minister Benjamin Netanyahu said earlier Monday that Israel stands “shoulder to shoulder” with the US “in mourning and sorrow.”

“On this terrible day, the people of Israel stand shoulder to shoulder with the American people in mourning and sorrow,” Netanyahu, who is also foreign minister, wrote on his Twitter account.

“Our hearts go out to the victims’ families and we wish a speedy recovery to the wounded. We grieve with you.”

Paris Mayor Anne Hidalgo tweeted that the Eiffel Tower will go dark on Monday night in tribute to the victims of the Las Vegas shooting, as well as a stabbing Sunday in Marseille in which two women were killed.

“Tonight we will turn off the Eiffel Tower from midnight in homage to the victims of the attacks in Marseille and Las Vegas,” Anne Hidalgo wrote, adding the hashtag “we are united.”

The City of Light has repeatedly switched off the night-time lighting on its most famous landmark to show solidarity with victims of terror attacks from London to Kabul.

Russian President Vladimir Putin expressed his condolences in a message to US President Donald Trump, saying a deadly mass shooting in Las Vegas was “shocking in its cruelty.”

“The crime that has taken the lives of tens of peaceful civilians is shocking in its cruelty,” Putin said according to a statement from the Kremlin.

It said the Russian president had expressed the words of support to the families of the victims.

Palestinian Authority President Mahmoud Abbas, in a cable to Trump, also sent his condolences to the victims of the shooting in Las Vegas.

“On behalf of the State of Palestine and its people, [Abbas] expressed his sincere sympathy to the families of the victims and his solidarity with them and wished the injured a speedy recovery,” the cable said, according to a report from the Wafa news agency.

Trump himself called the shooting an “act of pure evil” and said US flags would fly at half mast in honor of the victims.

Trump and First Lady Melania Turmp will lead a moment of silence later Monday afternoon on the White House South Lawn.

The US president also spoke Monday with British Prime Minister Theresa May about the shooting. The White House said May conveyed her condolences for those killed and wounded at the outdoor country music festival in Las Vegas.

The White House said the president thanked May and praised the first responders in Las Vegas who responded to the shooting.

British Foreign Secretary Boris Johnson earlier tweeted that he was “horrified by awful and indiscriminate Las Vegas attack.”

No motive is yet known for the shooting, which was carried out by 64-year-old Stephen Paddock.

While the Islamic State terror group claimed responsibility for the attack, the FBI said Paddock had found nothing connecting him to any international terrorist group.
