BBC cameraman Cumbers, 36, was shot dead by unidentified gunmen near Riyadh, the capital of Saudi Arabia. BBC security correspondent Frank Gardner, 42, was critically injured in the attack.
Cumbers, an Irish freelance cameraman on assignment for the BBC, was with Gardner and a Saudi government minder as he filmed a house belonging to an al-Qaeda militant killed by Saudi police in 2003, according to the BBC.
"A jeep, or jeep-like vehicle, drove up and somebody fired at the two Westerners with a machine pistol, with deadly consequences," said Sherard Cowper-Coles, the British ambassador to Saudi Arabia, as quoted by the BBC.
Al-Suwadi is regarded as a stronghold for religious extremists in Saudi Arabia.
