Saudi Arabia: What is King Abdullah's legacy?

Saudi Arabia is in mourning for King Abdullah, who died on Thursday.

His funeral has taken place in Riyadh, before a burial in an unmarked grave, in keeping with the kingdom's strict Muslim traditions.

His half-brother, Salman, has been confirmed as his successor. In his first televised address, the new King said there'd be no change of direction in the oil-rich kingdom.

He also called for unity in the Islamic world.
