Stocks are holding near their worst levels of the session with traders still on edge and very wary heading into the weekend break due to the tense geopolitical situation in the Northern Pacific.
That was despite a possible indication that China might not back-up its errant neighbour if it carries out a missile strike that could threaten US territory.
According to the English-language Global Times, which was founded by the Communist Party's People's Daily, China should "make clear that if North Korea launches missiles that threaten US soil first and the US retaliates, China will stay neutral."
Despite that, as of 1207 BST the FTSE 100 was trading lower by 1.25% or 92.60 points to 7,297.51.
On the other hand, COMEX-traded gold futures were little changed, edging higher by 0.22% to $1,293.00/oz.. Yet the FTSE 100 volatility index continued to climb higher, adding 17.13% to 15.93, a clear reflection of investor caution.
Meanwhile, the pan-European Stoxx 600 was on track for a greater than 2% loss for the week, its worst showing since November.
Commenting on the situation in markets, LCG Head of Research Jasper Lawler said: "Love or loathe him, Trump isn't one to back down from a confrontation so its perhaps not a surprise that things have escalated. North Korea responding with a threat to US territory after Trump warned them not to threaten the US was never going to go down well.
"We assume markets will move on if it remains purely a war of words but the sell-off looks durable. With earnings season almost over, worry over North Korea may have ignited a well-overdue period of greater market volatility."
The downwards pressure on the US stock market increased overnight after US president Donald Trump told journalists he stood by his warning made to the North Korean regime the day before. Indeed, Trump added that his warning may not have been "tough enough" and declined to take the option of a pre-emptive strike off the table.
On that note, the Global Times also pointed out that: "if the US and South Korea carry out strikes and try to overthrow the North Korean regime and change the political pattern on the peninsula, China will prevent them from doing so."
Back in the UK, in an interview with the Evening Standard the Monetary Policy Committee's Michael Saunders said Brexit would likely crimp the UK economy over the longer-term.
According to Saunders, Britain's gross domestic product may grow five percentage points less over the next 15 years.
On the economic calendar for Friday, US consumer price data for July are expected at 1330 BST, followed by speeches from the presidents of the Federal Reserve banks of New York and Minneapolis at 1440 BST and 1630 BST, respectively.
