A terminal at Newark Liberty Airport was evacuated twice early Monday when a fire broke out in a ceiling and then later reignited.

A spokesman for the Port Authority of New York and New Jersey confirmed that fire began just after 1 a.m. in a boiler room in Terminal B.

Port Authority spokesman Steve Coleman said about 200 people evacuated, including passengers on a Cathay Pacific flight as well as service and airport workers. There were no injuries, but there was significant smoke in the terminal, which had to be ventilated, he said.

The first fire was extinguished about 2 a.m. and the terminal reopened, Coleman said, but it rekindled about 3 a.m. and had to be evacuated again.

The terminal was reopened about 5:30 a.m. As a result of the fires some flights that regularly use Terminal B — primarily Delta — had to be moved to other gates and travelers should check with their airline for further information , Coleman said.

Coleman said the cause was believed to be electrical.
