New York City police officials have beefed up security at strategic locations in the city in response to the bombings that have killed at least two people at the Boston Marathon.
The New York City Police Department said it has increased its presence at hotels and certain other locations in the city as a security precaution.
Until more information is gained about the Boston incidents, NYPD may react accordingly.
NY1 local television reported that the Metropolitan Transportation Authority will upgrade police presence at subway stations, tunnels and bridges.
"As law enforcement authorities investigate today's explosions in Boston, I ask all New Yorkers to keep the victims and their families in your thoughts and prayers," New York Mayor Michael Bloomberg, a Boston native, said in a statement.
"We have 1,000 members of the NYPD assigned to counter-terrorism duties, and they – along with the entire NYPD and the investments we have made in counter-terrorism infrastructure – are being fully mobilized to protect our city."
New York Gov. Andrew Cuomo said in a statement: "Our thoughts and prayers are with the people of Boston and Massachusetts as reports come in on the horrific tragedy at the Boston Marathon.”
Cuomo added that the New York National Guard had dispatched three vehicles and six soldiers to help support the Boston marathon on Sunday. They remain in Boston to help with the cleanup efforts.
