Istanbul: Ukrainian government said Friday it has information that far-right radical groups in the country could be planning a terror attack.

“The far-right radicals are preparing to disturb the peace again and they will not stop short of anything, even a terror attack,” Xinhua quoted Interior Minister Vitaliy Zakharchenko as saying.

The protests in Ukraine began last November against the government’s decision to put on hold an association agreement with the European Union.

However on Friday after the Winter Olympics started, a passenger aboard a commercial airline flight from Ukraine to Turkey tried to hijack the airplane Sochi in Russia.

Reportedly he threatened to set off a bomb with a cellphone if his demands were not met, but the crew fooled him and the other passengers into thinking the plane had landed in Sochi when it was actually in Istanbul, passengers and the authorities said.

The man who was a 45-year-old Ukrainian, was seized by special security forces as the Turkish aircraft, a Pegasus Airlines Boeing 737-800 with 110 passengers, was being evacuated at Sabiha Gokcen Airport, according to Huseyin Avni Mutlu, the governor of Istanbul.
