Egypt's Karnak temple 'targeted in suicide bomb attack'

A suicide bomber has blown himself up near a tourist site in the Egyptian city of Luxor, security sources and witnesses say.

Three assailants were killed in the attack, which took place close to the ancient Karnak temple, one of Egypt's most popular tourist destinations.

Two gunmen were shot dead by police, but a third person managed to pass through a barrier leading to the site before blowing himself up.

Four Egyptians - including shop owners and police officers - were wounded in the attack.

No group immediately claimed responsibility.
