The most significant tomb was that of Huy, Viceroy of Kush under the famed King Tutankhamun. Inside the tomb, wall paintings depict a great festival with southerners from Nubia paying tribute, confirming Egypt's domination and the authority of local rulers.
"The tomb also shows Huy receiving the seal of his office, and other unparalleled details regarding the administration of Egypt's most important foreign holdings," said John Darnell of Yale University.
Antiquities Minister Mamdouh Eldamaty said the newly opened tombs, in the Qurnat Marey area of Luxor, are among the most important ones built for nobles of the New Kingdom period, which ended over 3,000 years ago.
The opening, planned before the airline disaster, is part of government plans to highlight new archaeological sites to encourage tourism.
The cause of Saturday's crash of a Metrojet flight packed with Russian vacationers returning home from the Red Sea resort of Sharm el-Sheikh is under investigation, but the Islamic State extremist group has claimed responsibility and British Prime Minister David Cameron said it was "more likely than not" that a bomb brought down the flight. All 224 on board were killed.
"It is very sad what happened, but we have to wait or the result of the investigation," Eldamaty said before descending into Huy's tomb. "It was not a terror act, it was an accident," he said, voicing the official narrative that many Egyptians in tourism-dependent areas have come to espouse with a sometimes desperate hopefulness.
