The Afghan Taliban has once warned the US that "US President Donald Trump has failed to understand what nation he is troubling."
Taliban spokesman Zabihullah Mujahid told the US president in a tweet, "Trump is very careful."
"Trump still has difficulty understanding what kind of nation he is dealing with," he said.
Zabihullah Mujahid added that "Trump's advisers must understand that Afghanistan will be a graveyard for them".
Just hours before Taliban's tweet, a suicide attack in Kabul killed 4 workers.
A few days ago, Trump had announced a secret meeting with Afghan President Ashraf Ghani and the Taliban at Camp David, suspending talks with the Taliban.
The Taliban in its response said that the cancellation of the talks would hurt the United States more than ever.
On September 9, US President Donald Trump spoke of the 9/11 attacks in reference to the Afghan war, saying he would target the Taliban in a 'worst' way, something that has not been exemplified in the past.
Addressing a ceremony held on the eve of the 9/11 attacks, Donald Trump said, "In the last four days, US forces have targeted the enemy in a way that has never been targeted and will continue." '.
Donald Trump, without explaining the nature of the target, said that it was ordered after talks with the Taliban were canceled in response to an American soldier killed in an attack in Afghanistan last week.
Such statements came from Al-Qaeda, the organization that claimed responsibility for the 9/11 attacks, and a video released by them said that the interests of the United States, Europe, Israel and Russia would be attacked.
