An Emirates plane that landed at JFK Wednesday morning has been quarantined after more than 100 of the 500 passengers on board fell ill, according to NBC 4 New York.

Emirates flight 203 from Dubai was headed to New York when at least 100 of the 500 passengers on board reported feeling ill.

The flight landed at JFK Wednesday morning about 9:10 a.m. where Port Authority Police and the Centers for Disease Control and Prevention were waiting  to check passengers in a staging area.

NYC Mayor Bill de Blasio's office confirmed that the passengers had been quarantined.

One passenger posted a photo showing more roughly a dozen emergency response vehicles waiting on the runway. The passenger, Larry Coben, said passengers were warned that some people on the flight had become sick, but he said he hadn't seen any sick passengers. However, he noted that the plane contained two levels of seats.
