Given that the Taliban had been waging attacks throughout the talks, some critics have questioned why Trump called them off and whether he should have made such a public show of his displeasure.
Taliban spokesman Zabihullah Mujahid issued a statement claiming responsibility for the attack, which he said killed more than 200 commandos. The massive air campaign initially targeted troops, training camps and air defenses of the Taliban, which ruled Afghanistan under a harsh version of Islamic law from 1996 and hosted Osama bin Laden as he masterminded the September 11 attacks.
"Then the attack, the anguish of knowing your family member had boarded one of these flights or was working at the World Trade Center or serving right here at the Pentagon".
Shaheen in a wide-raging interview with the Taliban official "al-emarah" website said Trump's unexpected tweets were surprising for the Taliban negotiators as they were waiting for the formal announcement of the peace agreement.
The US Embassy compound in Kabul, Afghanistan, was hit by a rocket during the first few minutes of the 18th anniversary of 9/11 on Wednesday.
He recounted how he called off the talks after the Taliban admitted carrying out a bombing in Kabul that killed Army Sgt. Elis A. Barreto Ortiz. I have a different opinion than they do - that's not unusual.

Crawford: The Trump administration's approach to negotiations gets mixed reviews in my book.
"The global community needs to continue its support by fulfilling the commitments made to the Afghan security forces in their fight against the scourge of terrorism", he said. The United States and Afghan government have been steadily losing ground and controlling less of Afghanistan.
India has been supporting a national peace and reconciliation process which is Afghan-led, Afghan-owned and Afghan-controlled.
Mr Trump has said he wants to withdraw around 5,000 of the 14,000 United States military personnel still in the country. The only real path to peace has always been a process that meaningfully involves the Afghan people and all the myriad stakeholders, including the government and political parties in Kabul.
It came after months of painstaking, mostly behind-the-scenes negotiations on cutting back the USA troop presence and extricating the United States from a long, fruitless war. The talks, however, excluded the Afghan government, as the Taliban considers it a U.S. puppet. Sure, but the Taliban had been clear that a ceasefire will be with those who can bring peace by withdrawing the occupation forces from Afghanistan.
