Egyptian security sources said there was no indication that the plane had been shot down.
An IDF spokesperson said Saturday that the army is coordinating with both Russia and Egypt to help locate the remnants of a Russian plane that crashed in the Sinai earlier in the day.
The IDF sent out surveillance aircraft to comb the area where the plane is believed to have crash landed. The IDF added that it would be ready to offer further assistance to Russia and Egypt if necessary.
In addition, Magen David Adom offered 30 of its ambulances and its air lift helicopters to assist Egyptian first responders following reports that there were still survivors at the crash site.
However, it was later reported that no survivors were found at the scene.
