Russia Plane Crash Update: Moscow Bans Incoming EgyptAir Flights As Investigation Reveals Few Answers In Deadly Disaster

Russia's state aviation agency has barred EgyptAir, Egypt's national airline, from flying into the country starting Nov. 14, Reuters reported. The change comes after the crash of a chartered flight bound for St. Petersburg from Sharm el-Sheikh, Egypt last month. All 224 passengers on the flight were killed.

Russian President Vladimir Putin decided on Nov. 6 to suspend all Russian flights to Egypt, the New York Times has reported. However, he still promised to bring home some 20,000 of its citizens still in Sharm el-Sheikh, a resort city located on the southern tip of the Sinai Peninsula. The cause of last month's crash remains unclear, with the U.S. and U.K. maintaining that terrorism could have been the culprit. The plane fell apart midair , and a local affiliate of the Islamic State militant group has claimed responsibility for the crash.

Many airlines have also suspended flights from the United Kingdom to Sharm el-Sheikh, including Monarch, easyJet and Thomson Airways through Nov. 25, the BBC reported. British Airways has suspended bookings until Nov. 23, while Danish airline SAS has canceled all flights to Sharm el-Sheikh until further notice. The Lufthansa Group has also suspended all flights to and from the Sinai peninsula until further notice, including two weekly flights arriving and departing from Sharm el-Sheikh.

EgyptAir has maintained that its flights are running smoothly. The most recent news posted to the airline's website on Nov. 7 informed customers that all flights are on schedule.

The investigation into the cause of the crash has come under criticism in recent days for a lack of transparency. Some say could it could affect evidence critical in determining the cause of the crash.

Although bodies have been repatriated to Russia, it's unclear whether autopsies have been performed on them, the Wall Street Journal reported. Autopsies could reveal clues about the causes of death and prove whether there was indeed a bomb on the aircraft.
