JK Rowling spoke out on Twitter after the London Bridge terror attack
The 51-year-old responded to an article by the US media outlet when they tweeted a headline early Sunday morning that said: "The London attacks hit a nation still reeling from the shock of the bombing in Manchester almost two weeks ago."
The author responded in defence of the country's attitude to the attacks, after a number of people took to Twitter criticising the publication.
"The thugs who mowed down innocent people would love to think of the UK 'reeling' but it isn't. Don't confuse grief with lack of courage," Rowling said.
The attack occurred Saturday night when three knife-wielding terrorists rammed a van against a number of people on London Bridge and proceeded to get out and stab many more. Seven people died and 48 others were injured, with several still in critical condition.

If we need an alarmist blowhard, we'll call
The Gloucestershire native, who has been very vocal about her feelings on US President Donald Trump, also weighed in on his comments about the attack.
Trump tweeted: "At least seven dead and 48 wounded in terror attack and Mayor of London says there is 'no reason to be alarmed!'"
"It's called 'leadership', Donald. The terrorists were dead eight minutes after police got the call. If we need an alarmist blowhard, we'll call," Rowling fired back.
