Six tourists were killed and 39 rescued when a submarine sank in the Egyptian Red Sea, the local governor confirms
The accident happened around one kilometre off the coast of Hurghada
The governor says the tourists were from Russia, Norway, Sweden, and India - all six who died were Russian
In November, a tourist boat called the Sea Story sank in Hurghada, leaving 11 dead or missing - including a British couple - and 35 survivors
The question is why these incidents keep happening, writes Sally Nabil from Cairo
One person who went on the submarine last month tells us he "never felt unsafe" - while another tourist shares recent footage of a trip with the same company

We're still waiting to get more details on the incident, but the Russian Embassy in Egypt says that all of the tourists on board were Russian.
In a post on Facebook, it says 45 passengers were on the vessel, including children.
The post adds that four people have died, and they are waiting for information on several more passengers.
The incident happened at around 10:00 local time, around 0.6m (1km) from the shore, it says.
As a reminder, sources have told the BBC that six people are feared dead. We've contacted officials in Egypt, as well as Russia, to find out more and we'll bring you the latest as we get it.
The tourist submarine sank off the Egyptian Red Sea city of Hurghada early on Thursday, the BBC understands.
The city is a popular tourist destination known for its beaches and coral reefs.

Sindbad has been running tourist trips in the Hurghada area for several years.
The company says it holds two of the only "14 real recreational submarines" in the world.
The company allows tourists to travel 25 metres (82 feet) deep in the sea to explore "500 metres of coral reef and its marine inhabitant".
The website for Sindbad Submarines continues: "It offers 44 passenger seats - two pilots' seats and a sizable round viewing window for each passenger."
This is not the first incident involving tourist boats in Hurghada.
In November, a tourist boat called the Sea Story sank, leaving 11 dead or missing - including a British couple - and 35 survivors.
At the time, Egyptian authorities attributed the disaster to a huge wave of up to 4m (13ft) - but the BBC spoke to survivors who said there were safety issues.
UK investigators said last month there had been 16 incidents involving "liveaboard" vessels in the area in the last five years, with a number resulting in deaths.
