INTERNATIONAL NEWS - A sharp rise in fresh virus infections in the US and elsewhere sparked a hard sell-off in equities Thursday, following hefty losses on Wall Street and in Europe.
Concerns about a possible trade battle between Washington and Europe added to the downbeat mood on trading floors, with a warning from the International Monetary Fund over the global outlook also souring sentiment.
A three-month surge across world markets, supported by the easing of lockdown measures and a wall of government cash, is showing signs of stalling as the killer virus sees a resurgence and raises questions about the pace of reopening.
A key worry is the US, where dozens of states including Texas, Florida and Arizona have seen a spike in infections in recent days.
Some US officials who loosened restrictions on business, dining, public gatherings and tourism are now urging residents to again stay home.
Disneyland, near Los Angeles, delayed its planned July 17 reopening without announcing a new reopening date for the world's second-most visited theme park, while Apple and Nike have closed stores that had recently reopened.
The issue is becoming so bad that New York, Connecticut and New Jersey said they will impose a 14-day quarantine on people arriving from areas with high infection rates.
Elsewhere, Australia's military announced it would send 1,000 troops to Melbourne to help contain the country's only significant outbreak over fears of a second wave.
And around 640,000 people in two German districts were facing new containment measures after an outbreak at a slaughterhouse.
Experts warn that an early summer heatwave across Europe could lead to a surge in infections as people hit beaches and parks while ignoring social distancing measures.

Hong Kong and Shanghai were closed for holidays.
The financial devastation wrought by lockdowns was laid bare Wednesday by the IMF, which said the crisis would shrink the global economy by 4.9 percent this year and wipe out a mind-boggling $12 trillion over two years.

That came just days after the EU indicated it plans to press ahead with a digital tax that would primarily hit US tech firms.
Trade officials listed products from France, Germany, Spain or Britain, ranging from olives to decaffeinated coffee, as possibly subject to the new levies.
But while the development, which comes on top of growing concerns about tensions between China and the US, is a worry, AxiCorp's Stephen Innes said the spike in infections was crucial.
"It is worth noting the US administration's proclivity to walk-back trade frictions," he said in a note.
