Intense concern is raised by reports that jihadist Islanic State members are planning to “hit” five passenger planes in Europe during the Christmas season.

A senior official stated to British newspaper “Sunday Express” that many “await for something catastrophic, very soon” implying that it is quite possible that ISIS will pull off their threats.

Authorities in Europe, according to the same source, are informed that jihadists will hit five airplanes in five European cities during the holidays.

“We expect and are preparing for a big hit”, he said, while, according to international media, this information was first revealed by the British authorities.

Sources from major European airports reported that they received information stating that ISIS was planning to transport powerful bombs inside luggage.

For this reason, according to the report, the authorities are considering banning the transportation of devices such as smartphones and iPads.

According to experts, the mobile phones can be used to set the bombs off.
