The World Health Organization is keeping a close watch on a disease outbreak in Saudi Arabia.

The outbreak was caused by a virus that's in the same family as the one that caused SARS.

Two people have died of the disease, and test results are pending on a third suspected case.

The infections were caused by a newly identified coronavirus.
   
A coronavirus also caused the 2003 SARS outbreak, which killed 44 people in Toronto and about 775 people worldwide.
