Lebanon has allowed Austrian officials free access to the ambassador's house
Police called to the home of Lebanon's ambassador to Austria have found the body of a woman in the cellar.
The woman had apparently been stabbed to death. Police did not name the victim, but believe she was the house's 30-year-old Filipina housekeeper.
They say the body, which had several stab wounds, was discovered by the cook - the only person in residence.
A Vienna police spokeswoman said the ambassador, Ishaya El Khoury, is currently out of the country.
The spokeswoman told Reuters news agency that investigators were searching the scene and interviewing witnesses.
"It was murder. There are multiple stab wounds," she added.
No-one has so far been arrested.
The Lebanese authorities are allowing Austrian police officers free access to the scene, even though an ambassador's residence would not normally fall under Austrian jurisdiction.
