ISIS clams Resposibility of the Russian plane in Egypt. Read full details.

Moscow - Russia's Investigative Committee said on Saturday that it was checking fuel samples from the last refueling stop, in the Russian city of Samara, of an airliner that crashed in Egypt, RIA news agency reported.

The committee's spokesperson, Vladimir Markin, also said investigators were questioning people who were involved in preparing the aircraft and its crew and carrying out searches at Moscow's Domodedovo airport where the airline that operated the plane is based.

Earlier in the day the committee said it had opened a criminal case against the airline.

Meanwhile a militant group affiliated to ISIS in Egypt claimed responsibility for the downing of the Russian passenger plane.

The claim of responsibility was also carried by the Aamaq website which acts as a semi official news agency for the Islamic State.
Egyptian security sources earlier on Saturday said early investigations suggested the plane crashed due to a technical fault.
