From Washington, this is VOA news. I'm Jonathan Smith reporting.

President Trump led a moment of silence at the White House on Monday to remember the victims of Sunday night's mass shooting in Las Vegas, Nevada. It was the worst mass shooting in American history. At least 58 people are dead and 515 are wounded.

Police and federal investigators still do not know the motive for why the man they say 64-year-old Stephen Paddock of Mesquite, Nevada, opened fire on a crowd of more than 22,000 attending a country music show.

Paddock's brother, Eric in the southeastern state of Florida, says he doesn't know why it happened, either.

"I, I, there is not even anything I can say, I mean, how do you? I mean my brother did this. I, this is like it was done, you know, like he shot us."

President Trump addressed the nation. He thanked Las Vegas police for their sacrifices and quick responses during the attack.

"It was an act of pure evil. The FBI and the Department of Homeland Security are working closely with local authorities to assist with investigation and they will provide updates as to the investigation and how it develops."

Police forced their way into the shooter's hotel room and found him dead. It's believed that paddock killed himself. Police found at least 10 rifles in his room.

U.S. Senator Dean Heller, who represents Nevada, called the shooting a senseless and horrifying act of violence.

More than 16 people are reported dead in twin suicide attacks on a police station in Syria's capital, Damascus.

Syria's interior minister told reporters that two "terrorists" attacked the police station in the al-Midan neighborhood of Damascus with a number of bombs on Monday before one of them blew himself up. The other bomber made it inside the compound, where police killed him, causing his bomb to explode.

There has been no claim of responsibility.

The U.N. high commissioner for refugees says the granting of asylum to people fleeing war and persecution is eroding as states increasingly use refugees as a political football to further their local and national interests.

Correspondent Lisa Schlein reports for VOA now from Geneva at the opening of the UNHCR's annual week-long refugee conference.

The U.N. refugee agency reports a record 65.6 million people were forcibly displaced by war and persecution worldwide at the end of last year, including 22.5 million refugees who had crossed international borders.

In a somber assessment of the current global situation, U.N. refugee chief Filippo Grandi notes in just five weeks, half a million Rohingya refugees have fled terrifying violence in Myanmar.

"Principled leadership has frequently given way to an erosion of refugee rights, driven by confused and sometimes frightened public opinions often stirred up by irresponsible politicians."
