A suicide bomber blew himself up Wednesday outside the ancient Karnak temple in southern Egypt in an attack that left four people, including two police officers, wounded.
Officials said the attack involved two other people who were killed by police, and that none of the wounded were tourists.
?The temple in the city of Luxor is part of a on the banks of the Nile river that is a major tourist attraction for both foreign and Egyptian tourists.
The tourism industry has been hard hit since early 2011, when a popular uprising toppled longtime strongman Hosni Mubarak after three decades in power.
Wednesday's attack was the second this month by suspected Islamic militants at or near a major Egyptian attraction. On June 3, gunmen on a motorcycle opened fire outside the famed Giza Pyramids on the outskirts of Cairo, killing two police officers.
Luxor Governor Mohammed Sayed Badr said the nationalities of the three men have yet to be determined.
There was no immediate claim of responsibility.
Islamist militants have carried out repeated gun and bomb attacks in Egypt's Sinai Peninsula in recent years, mainly targeting security forces.
Those attacks have increased since then-army chief and current President Abdel-Fattah el-Sissi led the ouster of Islamist President Mohammed Morsi in 2013.
In 1997, 58 tourists and four Egyptians were killed in an attack in Luxor at the 3,400-year-old Hatshepsut Temple honoring a female pharaoh.
