A German passenger plane carrying 140 passengers  to the Egyptian Red Sea resort of Hurghada landed was forced in land in Hungary following a bomb scare on Monday.

Upon landing in Budapest, the Hungarian police officers boarded the Boeing to search for suspected explovies. "No explosives or bomb-making equipment were found, state news agency MTI reported.

The Airbus A321 from Berlin was diverted to Budapest after an "unspecific warning given by telephone," local reports said.

The passenger plane is operated by Condor Flugdienst, more commonly known as Condor, which is a German leisure airline based in Frankfurt.  The airline operates scheduled flights to leisure destinations in the Mediterranean, Asia, Africa, North America, South America and the Caribbean.

Since the downing of the Russian jet in the Egypt's Sinai region on 31 October, security services have been on a high alert. 

The Islamic State (Isis) terrorists last month in the latest issue of its propaganda magazine - Dabiq, published the photos of the bomb which it claimed brought down the Russian plane, killing all 224 on board. The bomb apparently was planted in a Schweppes can.

The downed Russian passenger plane, which was an Airbus A321 operated by Metrojet, was taking back the Russian holiday-makers from Sharm al-Sheikh in Egypt to St Petersburg when it blew-up mid-air over the Sinai Peninsula.
