Abbey Gate: The Twelve Days Before the Bomb

The bomber did not simply appear at Abbey Gate. He had to be selected, moved, prepared, supplied, and brought through a security environment surrounding one of the most heavily watched locations in Afghanistan. The names matter because accountability begins with knowing who was involved.

August 14: authorization.

Two days before Kabul fell, senior Taliban and al-Qaeda figures met in the Band-e-Timur area of Maiwand district in Kandahar Province. According to the reporting underlying this brief, the meeting included Mullah Mohammad Yaqoob Mujahid, Mullah Tajmir Jawad, Hafiz Abdul Hafiz Haqqani, Abdullah bin Laden, Mawlawi Abdul Rahman Akhundzada, Mullah Matiullah Mubarak, and Sheikh Abdul Hakim Ishaqzai. A sharia ruling authorizing a suicide attack against U.S. Marines during the evacuation was issued.

The meeting connected generations of the same networks. Mullah Yaqoob is the son of Taliban founder Mullah Omar. Hafiz Haqqani is a relative of Sirajuddin Haqqani and a senior Badri 313 commander. Abdullah bin Laden is a son of Usama bin Laden and, according to the reporting used for this investigation, was then involved in al-Qaeda’s military leadership. Twelve days before the blast, the attack had moved from intent to authorization.

August 15: Kabul falls and the prisons open.

When the Afghan government collapsed, prisons across the country opened. Among the prisoners released from the Parwan Detention Facility near Bagram was Abdul Rauf Sangari, also known as Abdul Rahman al-Logari, the name later used in the Islamic State claim for the Abbey Gate bomber.

Sangari had previously been recruited by ISIS, trained in Pakistan, and sent to India, where he was involved in reconnaissance for potential attacks before being captured and returned to Afghanistan. According to the investigation underlying this brief, his release was part of a wider release of ISKP personnel as the former Afghan government collapsed. He was selected for the Abbey Gate mission and moved toward Kandahar.

August 16–18: the bomber is prepared and moved to Kabul.

In Kandahar, Sangari was briefed by senior ISKP figures, including former ISKP leader Aslam Farooqi and Mawlawi Rajab Salahuddin. Two other operatives, Hazrat Ali and Mustafa Irfan Afridi, were part of the cell as contingencies. Sangari remained the primary bomber.

At the same time, Taliban and Haqqani commanders were consolidating control in Kabul and around the airport. The investigation identifies a command-and-control hub at a Sirajuddin Haqqani guesthouse in the Shirpur neighborhood. It also identifies Badri 313 and other Haqqani-linked commanders involved in airport intelligence and security. On August 18, Sangari was moved from Kandahar to Kabul through a facilitation network and handed over for final preparation.

The security architecture became part of the attack route.

Once in Kabul, Sangari was shown information about the airport and the people he would encounter along the route. The central issue in this reporting is that the network planning the attack did not need the bomber to evade every checkpoint. It had influence over the security layers outside the airport.

The investigation places Said Sebghatullah Hashemi at the outer security layer, Muhammad Amin Jan Fathullah and Badri 313 in the middle, and Mohammad Saleem Saad overseeing day-to-day airport security and the final checkpoint. It also identifies Fathullah as involved in intelligence collection at the airport and in selecting Abbey Gate as the target because of the concentration of U.S. Marines.

August 23: the crowd and the bomb.

As the evacuation intensified, screening and crowd pressure shifted toward Abbey Gate. The result was more people, more congestion, and more U.S. service members concentrated at the location eventually attacked. The investigation also places Sher Mohammad, a former Haqqani-linked operative who later joined ISKP, at the Haqqani guesthouse on August 23 with the explosive vest used in the bombing.

By that point, the pieces were converging: the bomber was in Kabul, the gatekeepers were in place, Abbey Gate had been selected, the crowd was concentrated there, and the explosive device had arrived.

August 25: the warnings are everywhere.

By the day before the bombing, U.S. forces were receiving threat reporting about a possible attack around the airport. The reporting included suspicious surveillance, potential explosive devices, black backpacks, vehicle bombs, and concern that a suicide bomber could already be in the area. North Gate was closed after a threat was judged credible.

That night, Sangari was moved to a Haqqani safe house near the airport. The same reporting also identifies preparations for a second bomber, Mohammad Ali, with Hazrat Ali and Mustafa Irfan Afridi moving toward Nangarhar to support a possible follow-on attack.

August 26: Abbey Gate.

Abbey Gate was packed. Thousands of Afghans were pressed together outside the airport while American service members tried to identify evacuees and move families through the gate. A red umbrella became an informal point of orientation above the crowd.

Sangari moved through the security layers. The investigation identifies Hashemi, Fathullah’s Badri 313 positions, and finally Saad as the checkpoints he passed. It also identifies communications among senior Haqqani and ISKP figures as the bomber moved toward the target. At 5:36 p.m., Sangari detonated.

Thirteen American service members were killed: Staff Sergeant Darin T. Hoover; Sergeant Johanny Rosario Pichardo; Sergeant Nicole L. Gee; Corporal Hunter Lopez; Corporal Daegan W. Page; Corporal Humberto A. Sanchez; Lance Corporal David L. Espinoza; Lance Corporal Jared M. Schmitz; Lance Corporal Rylee J. McCollum; Lance Corporal Dylan R. Merola; Lance Corporal Kareem M. Nikoui; Navy Hospitalman Maxton W. Soviak; and Army Staff Sergeant Ryan C. Knauss. Nearly 170 Afghans were killed with them.

August 27: the second bomber.

The plot did not necessarily end with the explosion. On August 27, U.S. forces conducted an over-the-horizon strike in Nangarhar against an ISKP vehicle moving operatives toward Kabul. According to the investigation, Mohammad Ali, the second suicide bomber, and Mustafa Irfan Afridi were killed, while Hazrat Ali was wounded.

Five years later, the accountability question remains.

The public story of Abbey Gate has largely centered on ISKP and on the bomber identified in the group’s claim. The wider network reconstructed in this investigation is more complicated. It includes senior Taliban, Haqqani, ISKP, and al-Qaeda-linked figures involved at different stages of authorization, facilitation, intelligence, movement, security, and command.

Five years later, many of the senior figures identified in this reporting remain free. That is the distinction between identifying the organization that claimed an attack and understanding the network that made the attack possible.

There is a reason to end this brief with the red umbrella rather than the men who planned the attack. Before 5:36 p.m., Americans at Abbey Gate were still pulling people from the crowd, checking documents, helping families, passing water, and trying to get people to safety. Accountability matters because their names matter more.
