The April 2005 attacks were three related incidents that took place in the city of Cairo, Egypt, on 7 April and 30 April 2005. While the first killed three bystanders, the latter two incidents are generally considered to have been minor, in that they caused no loss of life other than those of the perpetrators and appear not to have been planned in advance. Neither sophisticated methods nor sophisticated materials were used in the incidents, and the Egyptian authorities have consistently described the attacks as "primitive".
