New photographs were released showing the Russian tourist jet which was crashed over Egypt’s Sinai peninsula last weekend and appear to prove that it was brought down by a bomb.

The Airbus A321 crashed shortly after taking off from the resort of Sharm el-Sheikh heading to St Petersburg, Russia and killed all 224 people on board.

As Daily Mail reports, the Russian newspaper Komsomolskaya Pravda published new images showing some holes in the wreckage of the plane which bear evidence of having been caused by something from inside the plane.

This follows news of further evidence suggesting that the crash was due of a bomb planted by Isis militants, according to U.S. and European security sources.

Russian newspaper Komsomolskaya Pravda has highlighted pictures of the Airbus A321 wreckage in Egypt showing pockmarks in the fuselage.

The holes ‘look like marks made by shrapnel’ and there are ‘holes in the plane parts with the edges curved inside-out.

‘We may suppose that these are the holes made by the destructive parts of the bomb,’ said the newspaper.

One image shows ‘small holes at the inner door of the emergency exit at the back part of the plane.

‘Such holes could have been made by metal balls, which are often used by terrorists as the destructive parts of the bombs.’

Although, Russian experts said that no signs of explosives had been found on the bodies of the victims, a Russian aviation official said they were looking into the possibility of an object stowed on board causing the disaster.
