UK Ambassador to Egypt John Casson has offered prayers for all passengers on board the Paris-Cairo flight that went missing on Thursday morning.

In a Twitter post Thursday, Casson posted EgyptAir phone numbers to help relatives of passengers. 

The national flag carrier has earlier said that Flight MS804 with 66 persons on board disappeared from radar 10 miles after entering the Egyptian air field.

Some 56 passengers along with 10 crew members were on board the Airbus A320.

Radar lost contact with the flight at 2:45 Cairo local time while it was at an altitude of 37,000 feet.

The flight took off from Charles de Gaulle airport on Wednesday 23:09 Paris local time then it disappeared from radar after entering the Egyptian airspace.

EgyptAir said that the captain had recorded more than 6,000 flying hours, including 2,000 hours in that model.

A well-placed source at EgyptAir said that 56 passengers, including 30 Egyptians, 15 French and two Iraqis, and 10 crew members were on board the missing plane.

The other passengers are from Britain, Belgium, Canada, Portugal, Kuwait, Saudi Arabia, Algeria, Sudan and Chad, the source added.
