Russian President Vladimir Putin has sent his personal condolences to President Donald Trump after Sunday night’s mass shooting in Las Vegas.

“The crime that took the lives of dozens of civilians is shocking in its cruelty,” Putin said in a telegram sent to the president. The message conveyed words of sympathy to the friends and families of the victims and wishing the injured a speedy recovery, the Kremlin said.

Putin’s message echoed those sent by other world leaders, including Mexican President Enrique Peña Nieto, who wrote on Twitter that he wanted to “express our most heartfelt condolences to the people of the United States for the terrible events.” Mexico’s consulate in Las Vegas was in contact with local authorities to support Mexicans affected by the attack, he added.

Meanwhile, in Israel, Tel Aviv City Hall was illuminated with the colors of the American flag to show solidarity with the victims, The Times of Israel reported.

"On this terrible day, the people of Israel stand shoulder to shoulder with the American people in mourning and sorrow,” Israeli Prime Minister Benjamin Netanyahu wrote on Twitter.

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

As condolences poured in from around the world, stories emerged of victims of the mass shooting sacrificing their own lives to protect their loved ones from the gunfire, in what White House press secretary Sarah Huckabee Sanders described as “the ultimate act of love.”

President Trump, addressing the nation, spoke of America's collective "grief," and said the shooter, Stephen Paddock, committed an act of evil. But he did not speak of any legislation that could restrict villains' ability to obtain such firepower. Paddock had 19 guns in his Mandalay Bay hotel room, authorities said.

All were, apparently, purchased legally.
