Crash or attack Jet broke apart 'midair'

(MENAFN- Arab News) PARIS: Aviation experts point to a range of scenarios to explain the crash Saturday of a Russian jetliner in Egypt's Sinai peninsula killing all 224 people on board.
International investigators have begun sifting through the wreckage and the Egyptian government says the plane's two 'black box' flight recorders have been recovered.
A senior Russian official Viktor Sorochenko says the plane disintegrated 'in the air.'
A militant group affiliated to Daesh in Egypt Sinai Province said in a statement it had brought down the plane 'in response to Russian airstrikes that killed hundreds of Muslims on Syrian land' but the Egyptian and Russian governments cast doubt on the claim. However Russia's Transport Minister told Interfax news agency the claim 'can't be considered accurate.'
Meanwhile Emirates Air Arabia and flydubai said on Sunday they were re-routing flights to avoid flying over Sinai. The airlines said they were closely monitoring the area and the re-routing was a security precaution. Re-routing usually means longer flying distance which adds to fuel costs.
Rescue teams scoured the area where the Airbus A321 came down on Saturday collecting into a pile the dead holidaymakers' belongings that were spread around the main part of the wreckage.
On Sunday morning about 100 Russian rescuers and investigators joined the search for remaining bodies and evidence to shed light on what happened.
Parts of the jet's wreckage were blackened and charred with one section forming heaps of twisted metal although the blue Metrojet logo was still visible on its broken tail.
