KABUL, Afghanistan — At first, the man was just walking across the street. Then he was running for his life. He managed four steps before the blast from the car bomb caught him.

Since then, the last few seconds of Akbar Fazelyar’s life, captured on video during a Taliban attack on Sept. 5, have become one of the most scrutinized moments in Afghanistan, slowed down and watched frame by frame on countless mobile phones and computer screens.

Though violent deaths are appallingly common in this country, Afghans have been seized with fascination and dread by the clip’s reminder of how little separates life from death.

In the United States, the Taliban attack in Kabul, the Afghan capital, was noted because President Trump cited it, along with the death of American and NATO soldiers in the blast, as the reason for calling off negotiations with the insurgents.
