Security has been increased in New York City and the Hudson Valley following word of an alleged terror plot targeting trains.

Yonkers police were patrolling Metro-North stations Friday, due to the city's high commuter population. The boosted security comes after Iraq's prime minister told reporters that the ISIS militant group is plotting to target subways in New York City and Paris.

No threat has been confirmed, but Yonkers police say they are working with state and federal law enforcement agencies to verify details. Police are also being rotated from one possible target site to another.

Commuters tell News 12 they do not mind the extra security, because it makes them feel safer when commuting on the train.

Police are already on high alert at synagogues in the Hudson Valley due to the Jewish High Holy Days that began this week.
