A total of 116 American tourists were traveling in three tour buses. The interior ministry said the middle bus - carrying 37 of the tourists - crashed into a parked dump truck loaded with sand.

Twelve of those injured were taken to Nasser Medical Institute in Cairo, according to the hospital's head, Dr. Bahaa Al-deen Ziad.

Two of the crash victims are in the hospital's intensive care unit in critical but stable condition, Ziad said. The 10 others were admitted to the hospital in stable condition and are being examined by doctors with specialties in neurosurgery, orthopedics and plastic surgery, he said.

Aswan is a popular tourist site in Egypt located about 1,000 kilometers (621 miles) away from Cairo.

The US Embassy in Cairo issued a statement on Sunday saying it was "deeply saddened" by the accident.
