Despite frequent terrorist attacks in the city, mainly by Taliban insurgents, the city continued to develop and was the fifth fastest-growing city in the world as of 2012. Until August 2021, the Afghan National Security Forces (ANSF) had been in charge of security in and around the city. Kabul was periodically the scene of deadly bombings carried out mostly by the Taliban but also by the Haqqani network, ISIL, and other anti-state groups. Government employees, soldiers and ordinary civilians have all been targets of attacks. The Afghan government called the actions of the terrorists war crimes. The deadliest attack yet was a truck bombing in May 2017. As of August 2021, the Taliban have been in control of the city after it was seized during the 2021 Taliban offensive.
