A suicide bomb attack has targeted the ancient Karnak temple in the southern Egyptian city of Luxor, officials have said.

The sources said no tourists were injured after the attack on Wednesday at the city frequented by millions of foreign and Egyptian tourists every year.

Officials said police have foiled two other suicide attacks also targeting the Nile-side temple, one of the country’s main tourist attractions, rivalling the pyramids at Giza.

The officials spoke on condition of anonymity because they were not authorised to speak to the media, the Associated Press news agency reported.

The Karnak complex is a vast open-air museum, and the second largest ancient religious site in the world, after the Angkor Wat Temple of Cambodia.

It is believed to be the second most visited historical site in Egypt with only the Giza Pyramids receiving more visits.

The attack comes a week after two police officers were shot dead by gunmen on a road leading to the Great Pyramids of Giza, just west of capital Cairo. (Al Jazeera)
