Egyptian investigators say they have so far found no proof that terrorism caused a Russian jet to crash in the Sinai in October, killing 224 people, the BBC reports.

The plane came down en route to Russia from the resort of Sharm el-Sheikh.

A group linked to so-called Islamic State (IS) said it bombed the plane. Nearly all the victims were Russians.

Russia has said a bomb brought down the Metrojet Airbus, after finding what it said were “traces of foreign explosives” on the debris.

It has vowed to “find and punish” the perpetrators. In response to Monday’s findings, Kremlin spokesman Dmitry Peskov re-iterated that “our experts concluded this was a terrorist attack”.
