Russia relies on assistance of its partners in finding and punishing those involved in the explosion of Russian A321 plane over Sinai, the country's President Vladimir Putin said, RIA Novosti reported.

He made the remarks during the meeting on the results of the investigation into Russian plane crash in Sinai, Egypt.

Earlier on Oct. 31, Airbus 321 of Russian airline Kogalymavia, which was flying from Egypt's Sharm El Sheikh to Saint Petersburg, crashed in Sinai.

The disaster, which is the largest in the Russian and Soviet aviation history, killed 217 passengers and seven crew members. Head of Russian Federal Security Service Alexander Bortnikov said that this was a terrorist attack.

The terrorists involved in the explosion of Russian aircraft will be found anywhere on the planet, said Putin.
