美国有线新闻 CNN 美国纽约和新泽西发生爆炸案 ISIS宣称对明尼苏达商城袭击案负责（在线收听）

CARL AZUZ, CNN STUDENT NEWS ANCHOR: First up this Monday on CNN STUDENT NEWS, apparent acts of terrorism on U.S. soil.

I'm Carl Azuz. Let's go.

Police in Manhattan, an island and a borough of New York City, are hunting for whoever set off an explosion that injured 29 people on Saturday night.

They'd all been released from hospitals by the next morning.

New York Governor Andrew Cuomo said it was obviously an act of terrorism, but then it happened when there was no specific threat against New York City from any terrorist organizations.

GOV. ANDREW CUOMO (D), NEW YORK: We will find who planted these explosives and they will be punished.

AZUZ: You heard him say explosives. Police believe the one that went off was hidden in or near a dumpster and officials found another device a few blocks away, a pressure cooker with wires and a cell phone attached to it. Police didn't know for certain if it was connected to the device that went off nearby.

They're also investigating whether any of this is linked to a separate explosion Saturday morning in New Jersey. It went off in a garbage can along the route of the U.S. Marine Corps charity run. But the run had been delayed and there was no one nearby or hurt in that blasts.

There were several people wounded though in an apparent terrorist attack in a mall in Minnesota Saturday. A man stabbed nine people at the Crossroads Mall in St. Cloud before he was shot and killed by police. Part of the Islamic State or ISIS terrorist group claimed it was responsible for that attack.
