Some of the most recent deadly attacks claimed by IS
In the deadliest attack to hit the Afghan capital since 2001, a suicide bomber targeted a crowd of demonstrators in Kabul on Saturday, killing at least 83 people and wounding another 231. The attack was later claimed by the Islamic State group. If the claim is proved correct, it will mark the first time the extremists have struck the Afghan capital.
