CAIRO, Nov. 5 (Aswat Masriya) - The British government agreed to resume flights on Friday to transfer British nationals stranded in Sharm el-Sheikh back to the UK, said British Prime Minister's spokesman Thursday. 

The decision came after talks between British Prime Minister David Cameron and Egyptian President Abdel Fattah al-Sisi, who is on an official visit to the UK, where they agreed to resume flights but with additional security measures including permitting passengers to carry hand baggage only and transporting hold luggage separately.

However, outbound flights from and to the UK are still suspended as per the government's advice "against all but essential travel by air to or from Sharm el Sheikh airport", added the spokesman in a statement. 

Travel agencies including Easy jet, Thomson Airways and Monarch will send out flights on Friday, but travel agencies will proceed with the suspension of flights until November 12.

The flight suspensions are based on intelligence information and advice Cameron received that "it's more likely than not" the Russian plane was downed by a bomb. 

The Russian-operated Airbus, carrying 224 passengers and crew, most of whom are Russians, crashed last Saturday in Egypt's North Sinai. 

The causes behind the crash remain unknown pending an international investigation and analysis of the plane’s black boxes.

IS affiliates in North Sinai claimed responsibility for the crash twice in separate statements, one of which was hours after the plane crash but was initially dismissed locally and internationally. 

In the second statement which was an audio recording released on Wednesday, the speaker said the downing of the plane marks the one-year anniversary of pledging allegiance to Islamic State fighters in Syria and Iraq.

Aswat Masriya couldn't independently verify the authenticity of the recording. 

Global intelligence firm Stratfor in an online report published Nov. 2, said that the "most probable explanation for the downed plane is the existence of an explosive device on board."

Stratfor added that Sharm el-Sheikh airport is known for its "poor" state of security.

Sisi said in a joint press conference with Cameron, that Britain had demanded ten months before the attack reassurances on the security procedures in Sharm el-Sheikh airport.
