Update: At 11:21 a.m. EDT: WNBC reports that LaGuardia has been given the green light and passengers are being allowed to reenter the terminal, and WCVB reports that Logan International Airport has also been OKed. 

LaGuardia Airport’s central terminal has been evacuated due to what airport police said was a suspicious package, Bloomberg News reports.

The news was confirmed by agency spokesman Steve Coleman, who said that a suspicious package was discovered early Tuesday morning, prompting the airport to clear the upper floor of its central terminal, according to CBS. Coleman added that a bomb squad was on its way to the airport, which sits on the waterfront of Flushing Bay in New York City's Queens borough.

ABC 7’s Eyewitness News reports that as of 11:05 a.m. hundreds of passengers were waiting outside the airport. The evacuation comes amid reports that all flights have been canceled from both LaGuardia Airport and Logan International Airport in Boston, where three bombs exploded during the Boston Marathon, killing three people, including an 8-year-old boy, and reportedly injuring more than 100.

At Logan, US Airways flight 1716, which was en route to Philadelphia, was also stopped on the ground Tuesday morning, and passengers were evacuated.

President Barack Obama was scheduled to deliver a live statement on the attack at the Boston Marathon from the White House at 11:30 a.m. EDT.
