Donald Trump and Hillary Clinton both refer to New York explosion as a bombing

Presidential nominees Donald Trump and Hillary Clinton addressed the explosion that injured 29 people in New York City on Saturday night, both initially identifying the events as a "bomb" or a "bombing," although officials have said it's too early to determine the cause of the blast.

"I must tell you that just before I got off the plane, a bomb went off in New York. And nobody knows exactly what's going on," Trump told the crowd at a Colorado Springs rally.

"We better get very tough, folks. We better get very, very tough," he added.

The explosion has been described as an "intentional act" by New York City Mayor Bill de Blasio, though he said there's currently no indication of a terror connection.

Police Commissioner James O'Neill said "the exact nature and cause of this explosion has yet to be determined."

Clinton, too, called the incident as a "bombing" when she spoke to media on her campaign jet:

"I've been briefed about the bombings in New York and New Jersey," she said, referring to both the Manhattan blast and the pipe bomb that detonated in a Jersey Shore town before a Marine charity run.

But when a reporter asked for her reaction on Trump citing a bomb as the cause of the explosion, Clinton replied that "it's important to know the facts about any incident like this."

"I think it's always wiser to wait until you have information before making conclusions," she added.
