The series featuring Pakistan, Afghanistan, and Sri Lanka was scheduled for November 17–29 in Rawalpindi and Lahore.
In a post on X, the ACB claimed that several lives had been lost in the attack, including three local cricketers who had been returning home after playing a "friendly" match in Sharana, the capital of Paktika province.
"The ACB considers this a great loss for Afghanistan's sports community, its athletes, and the cricketing family," the statement said.
Describing it as a "tragic incident", the ACB said that "as a gesture of respect to the victims" it was "decided to withdraw from participating in the upcoming Tri-Nation T20I Series."
This was set to be Afghanistan’s first tri-series on Pakistani soil and their second involving Pakistan this year.
The PCB has not yet issued a statement on the matter.
