The New York City Police Department released a photograph of Ahmad Khan Rahami, a 28-year-old New Jersey resident, as the suspect in the Manhattan explosion incident.

Rahami was described as a naturalized U.S. citizen who was born in Afghanistan on Jan. 23, 1988.

According to police, Rahami is about 5 feet 6 inches (about 168 cm) tall and weighs about 200 pounds (about 91 kg), with brown hair, brown eyes and brown facial hair.

"I want to be very clear that this individual could be armed and dangerous," said Bill de Blasio, Mayor of New York City.

Rahami is wanted because authorities believe he is the man seen carrying a duffel bag near the scene of Saturday's bombing in surveillance videos, according to local media.

Rahami's last known address was in Elizabeth in the state of New Jersey.

Just hours ago, a loud blast was heard at the Elizabeth train station, when a bomb squad was investigating a suspicious backpack found near the rail tracks. Some reports said it contained as many as five explosive devices.

Police are currently conducting raids in Elizabeth to search for evidence related to the explosive devices.

Another incident happened in Seaside Park, New Jersey, where a pipe bomb exploded along the route of a Marine charity run on Saturday.

The bombs found in the series of attacks over the weekend have similarities, said New York State Governor Andrew Cuomo.

The similarities include materials used in the bombs, cellphones used to trigger the bombs and "Christmas chain lights" found on the explosive devices, according to local media.

Cuomo also said that he "wouldn't be surprised if we found a foreign connection to the act."

The attacks put pressure on the city's law enforcement force as world leaders gather in New York City for the United Nations General Assembly this week.

Cuomo said on Saturday that New York State will deploy an additional 1,000 State Police officers and National Guard troops across the state.

Twenty-nine people were injured in the explosion in the Chelsea neighborhood of Manhattan on Saturday evening.
