Update: 11:28 a.m IST — The toll in Tuesday's bombing in central Kabul has been revised by TOLO News to "more than 20" from the earlier number of 24. The news channel also said on Twitter the blast was caused by a vehicle laden with explosives being detonated by a Talibani suicide bomber outside the Afghan secret service agency in Pul-e-Mahmood Khan area in central Kabul, and that a gun battle was underway in the area. 

President Ashraf Ghani condemned the bomb attack near the U.S. embassy and several other government buildings, calling it a terrorist attack. The Guardian quoted Taliban spokesman Zabihullah Mujahid as saying the jihadist group was responsible for the attack. The terrorist group had announced last week the beginning of its "spring offensive." 

The government had been attempting to begin peace talks with the Taliban.
