US national shot dead in Saudi capital Riyadh
RIYADH - A gunman killed a US national and wounded another in the Saudi capital of Riyadh on Tuesday, officials said, heightening Western concerns over security in the world's top oil exporter as regional unrest rises.
Police later shot and wounded an assailant and then arrested him, police said, adding there was no proven information of any ties between the man and "extremist" groups.
The apprehended man worked at the same company as the two victims and had recently been dismissed from his job, Saudi Arabia's embassy in Washington said in a statement.
