A powerful bomb hidden in a sewage tanker exploded in the morning rush hour in the centre of Kabul on Wednesday, killing at least 90 people, most of them Afghan civilians, wounding hundreds and damaging embassy buildings.
It was the latest in a series of deadly attacks, most of them claimed by either the Taliban or Islamic State, that have terrorized citizens of the Afghan capital.
Following are the most deadly attacks in Kabul over the past year.
May 3, 2017: Islamic State claimed responsibility for a suicide bombing that killed eight civilians in an attack on a convoy of NATO armoured personnel vehicles. The blast hit during the morning rush hour in one of Kabul's busiest areas. Officials said at least 25 people were wounded, with a number of civilian vehicles destroyed or badly damaged.
March 8: Gunmen dressed as medics attacked the 400-bed Sardar Mohammad Daud Khan hospital and battled security forces for hours, killing more than 50 people and wounding dozens in an assault claimed by Islamic State. A suicide bomber first blew himself up at the rear of hospital, across the road from the heavily fortified U.S. embassy, which provided the signal for three attackers with automatic weapons and hand grenades to open fire inside the complex, according to witnesses.

Islamic State claimed responsibility for the attack. Sept 5 A twin suicide bombing in a busy area near the Defence Ministry killed 35 people, including several senior security officers, and wounded 103.
