The 18th dynasty, part of the period of Egyptian history known as the New Kingdom, ended in 1292 BC and is considered among the most prosperous years of Ancient Egypt.

Piers Litherland of the University of Cambridge, head of the British research mission, said the tomb could be of a royal wife or princess of Thutmosid lineage.

Egyptian archaeologist Mohsen Kamel said the tomb's interior was "in poor condition".

Parts of it including inscriptions were "destroyed in ancient floods which filled the burial chambers with sand and limestone sediment", Kamel added, according to the antiquities board's statement.

Egypt has unveiled several major archaeological discoveries in recent years, most notably in the Saqqara necropolis south of the capital Cairo.

Critics say the flurry of excavations has prioritised finds shown to grab media attention over hard academic research.

But the discoveries have been a key component of Egypt's attempts to revive its vital tourism industry, the crowning jewel of which is the long-delayed inauguration of the Grand Egyptian Museum at the foot of the pyramids.

The country of 104 million inhabitants suffers a severe economic crisis.

Egypt's tourism industry accounts for 10 per cent of GDP and some two million jobs, according to official figures, but has been hammered by political unrest and the Covid pandemic.
