An explosion shook several blocks of Manhattan on Saturday night, injuring dozens of people, blowing out windows in the area, and rattling nerves across New York City.
“The early indication is this was an intentional act,” Bill de Blasio, the city’s mayor, said in a press conference near the scene of the explosion. But he added, “There is no specific and credible threat against New York City at this point in time from any terror organization.”
The explosion occurred near 135 West 23rd Street, between Sixth and Seventh avenues, which is a public housing complex for the blind.
James O’Neill, on his first full day as the city’s police commissioner, said the cause of the explosion has yet to be determined. In a sweep that evening, police located a plastic bag containing a pressure cooker with wiring and a cell phone a few blocks from the site of the explosion. It was unclear if the device was active or inert, reports the Wall Street Journal.
Local news reports said a dumpster outside the building exploded around 8:30pm local time. Images of a dented dumpster were tweeted from the scene:
At least 29 people were being treated for injuries, but none of them were life-threatening, officials said. The scene was calm in the aftermath of the explosion, as police and other officials secured the area and swept for explosive devices. Another area, a few blocks north, was also closed off by police investigating another possible explosive device.
Donald Trump, the Republican nominee for US president, immediately raised the specter of terrorism at a rally in Colorado Springs, Colorado. “Just before I got off the plane, a bomb went off in New York and nobody knows exactly what’s going on, but, boy we are really in a time,” he said soon after the explosion. “We better get very tough, folks.”
Earlier in the day, a smaller explosion disrupted a road race to benefit marines and sailors in Seaside Park, New Jersey. Nobody was injured, and officials said it was caused by “pipe bomb-style device.”
“Based on what we know at this hour,” de Blasio said, “there is no specific connection to the incident in New Jersey.”
