April 2005 Cairo terrorist attacks
Three related attacks took place in Cairo, Egypt, on 7 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.
