Saudi Arabia has recalled its ambassador to Libya over an alleged Libyan plot to assassinate Crown Prince Abdullah.
The Saudi Foreign Minister, Prince Saud al-Faisal, said he would also ask Libya to remove its ambassador from the kingdom.
The move is the latest sign of a deterioration in ties between Saudi Arabia and Libya, which denies the accusations.
In March last year, Libyan President Muammar Gaddafi publicly criticised Saudi Arabia at an Arab summit for hosting US forces ahead of their invasion of Iraq.
Details of the alleged plot to assassinate Abdullah, de facto ruler of the oil-rich kingdom, came to light earlier this year when an American Muslim activist pleaded guilty to illegal financial dealings with Libya.
He testified that he had been involved in a Libyan plan to kill the crown prince.
