Egyptian rescue teams at the site where a Russian civilian aircraft crashed in Sinai on Saturday have reportedly heard voices of people  from the wreckage, indicating that there may be a few survivors. 

A Russian airline Kogalymavia flight with 224 people on board crashed in a mountainous area in Sinai while flying from Sharm el-Sheikh resort on the Red Sea to Russia. 

According to Al Arabiya, the rescue teams have heard 'pained voices' from the wreckage. 

"We hope to find survivors especially after hearing pained voices of people inside," the rescuers were quoted saying. 

Most of the passengers on the plane were reportedly Russian tourists, and there were at least 17 children on board. 

Bodies of five children were extracted along with about 100 other bodies, with many found still strapped to their seats. 

"The plane split into two, a small part on the tail end that burned and a larger part that crashed into a rock. We have extracted at least 100 bodies and the rest are still inside," a  security officer told Reuters. 

"I now see a tragic scene. A lot of dead on the ground and many who died whilst strapped to their seats," he said. 

It is not clear what caused the plane to crash, though Russian agencies reported that the aircraft had developed technical problems and the crew had wanted to make an emergency landing. 

The Russian plane was at an altitude of 31,000 feet when it disappeared from air traffic control radars just 23 minutes into the flight.
