CAIRO: A bomb in Cairo wounded at least three people at an election event in support of Egyptian presidential frontrunner and former army chief Abdel Fattah al-Sisi, state-run newspaper Al-Ahram and security sources said on Saturday.

A man threw the homemade device in the direction of Sisi supporters, the sources said, adding that at least one of those injured was a policeman. Sisi, who was not present, is expected to win the presidential election on May 26-27.
