CAIRO (AP) -- Egypt's official news agency says a homemade bomb exploded at an election rally for presidential candidate Abdel-Fattah el-Sissi, wounding four people including two policemen.
El-Sissi, the front-runner in the May 26-27 vote, was not at the rally in the Cairo district of Ezbet el-Nakhl.
The late Saturday attack was the first to be reported on a campaign event for the retired field marshal who ousted Egypt's first freely elected president last July. El-Sissi has not appeared in any election rallies, apparently for security reasons, restricting his campaign to television appearances and interviews.
El-Sissi said in a recent TV interview that two assassination plots against him had been uncovered, but he gave no details.
His only rival in the vote is leftist politician Hamdeen Sabahi.
