Saigon Tourist, the tour company that organised the trip, said the Vietnamese tourists were “on their way to a restaurant for dinner” when the bomb exploded.
Company officials were heading to Cairo on Saturday and plans were made to allow some relatives of the victims to also fly to Egypt.
One of those heading to Cairo was Nguyen Nguyen Vu whose sister Nguyen Thuy Quynh, 56, died in the bombing, while her husband, Le Duc Minh, was wounded.
The couple, both aged 56, were in the seafood business and holidaying in Egypt when the tragedy occurred, Quynh’s younger brother said.
“We were all very shocked… My sister and her husband travel quite a lot and they are quite experienced in travelling abroad. Their hobby is travelling,” Vu told AFP.
‘Bring my sister home’
He said he was applying for a visa for Egypt and hoped to travel on Saturday. “Our wish is that we could bring my sister back home, and I hope that I can settle things well in the next 2-3 days.”
Friday’s deadly bombing was the latest blow to Egypt’s vital tourism industry, which has been reeling from turmoil set off by the 2011 uprising that forced veteran president Hosni Mubarak from power.
Egypt has been seeking to lure tourists back by touting new archaeological discoveries and bolstering security around archaeological sites and in airports.
It is also planning to open a major museum near the Giza pyramids — the only surviving structures of the seven wonders of the ancient world.
In July 2017, two German tourists were stabbed to death by a suspected jihadist at the Red Sea resort of Hurghada.
