Turkish Airlines plane resumed its trip to Istanbul around 6:50 a.m. AT Sunday after being diverted to Halifax Stanfield International Airport because of a bomb threat.

Five passengers were too afraid to re-board the plane and will have to make their own travel arrangements to get to Turkey.

No explosives were found on the Turkish Airlines plane, said RCMP.

Turkish Airlines Flight #2 was travelling from New York City to Istanbul when the threat was made.

RCMP searched the aircraft and luggage with police service dogs. At 4:25 a.m AT on Sunday the RCMP completed their search and no explosives were found.

The plane was then released back to Turkish Airlines, said RCMP.

There were 256 passengers and crew members on board, the Halifax airport tweeted early Sunday morning. There were no injuries.

That didn't stop some passengers from being disturbed by the threat, Fay Liu was one of five passengers who decided not to get back on the plane after it was cleared to leave Halifax.

"I have family and they're concerned and I'm not going because I am concerned, that they're concerned, that's all," she said.

Liu was on her way to Nepal to visit friends, now she simply wants to return to the U.S.

"I want to go home," she told reporters shortly before walking away.

The passengers disembarked about an hour later and were transported by bus to the terminal, where Spurway said they would be interviewed by the RCMP and processed by the Canada Border Services Agency.

This is the second flight diverted to Halifax due to a bomb threat in less than a week. On Tuesday night, a bomb threat forced Air France Flight 55 to divert to the airport with 262 people aboard.

Police searched the plane and found no explosives. That flight left Halifax on its way to France around 3:45 a.m. AT Thursday morning.

The Halifax Stanfield International Airport is no stranger to hosting planes in trouble. The airport has said it receives a couple of diverted planes every month, or about 20 in the run of a year.

Those planes divert to Nova Scotia for various reasons, including mechanical trouble or medical emergencies.
