De Blasio Tightens Security Following Orlando Shooting

New York City Mayor Bill de Blasio says security will be tightened at large gatherings following Sunday morning's shooting at a gay nightclub in Orlando. 

The mayor said there will be increased police presence at upcoming events like the Pride Parade, as well as at transportation hubs like Port Authority and Penn Station. de Blasio also promised more security near "key L.G.B.T. community institutions," particularly at Stonewall Inn - where the mayor will attend a vigil on Monday night.

"There are no credible threats to New York City," he said. "But at the same time, we are on high alert. There is no city in the world better prepared to stop terror and hate crimes."

In addition to increased security, Mayor de Blasio announced flags will fly at half-staff and City Hall will be illuminated in rainbow colors out of solidarity with the victims.

"This attack was not just an attack on human beings," the mayor said. "This was also an attack on our values."

Sunday's shooting was the worst mass shooting in American history, with 50 killed and at least 53 wounded. Police killed the gunman after a 3-hour standoff last night.
