As many as 19 people are thought to have died in the blast at a hotel in Taba, near the Egyptian border with Israel.
Charlie Meade is a British tourist who was in the hotel at the time of the explosion. He told BBC Radio 4's Today Programme what he saw.
I was in the main restaurant in the hotel, in the Hilton, and then the windows blew out - actually they blew in.
 Israeli officials said a vehicle loaded with explosives exploded |
We left the main restaurant area and fled as fast as we could to the safest area I could think of.
I was very lucky, I wasn't injured at all, but my partner had quite a lot of serious cuts from flying glass. She's OK though.
We were taken out of Taba about four hours after the explosion and we are now in another hotel.
We came out through the worst of the debris at the front of the hotel, where we were witness to what had actually happened.
The whole of the front of the hotel had been blown apart.
Rooms 01 to 04 from the first floor up to the tenth floor had completely disappeared.
The reality was that if you were in those rooms you would have very little chance of survival because there was nothing left of the front of the hotel.
We were with a member of the MFO (Multinational Forces and Observers) - an Englishman who works with the international forces in the Sinai desert.
He was absolutely clear that this was a bomb at the front of the hotel.
He was absolutely clear that this couldn't be a gas explosion.
It must have been a massive bomb, probably a car bomb.
