European markets all closed in the red. London's FTSE index dropped by 3.2%, while the Paris CAC fell 3.3% and the Frankfurt DAX slumped 4%. 

Dublin's ISEQ index sank by 2.6% to hit 6,397. 

Earlier in Asian trade, Tokyo's Nikkei index slumped 3.6% on rising fears the Olympics planned in July-August may be called off due to the coronavirus. The Hang Seng index in Hong Kong sank 2.42%, losing more than 4% since last Friday's close.
