One person was killed on Wednesday during clashes in eastern Cairo between supporters and opponents of the Muslim Brotherhood, state news agency MENA reported.
Violent clashes, in which petrol bombs and birdshot were reportedly used, erupted when locals attacked a march by Brotherhood supporters in the Ezbet Al-Nakhl area of Ain Shams.
Some 20 shops and the façade of a metro station were damaged during the fighting amid a reported absence of security forces. Metro services to the area were briefly interrupted.
Police were deployed in the area early on Thursday to prevent further clashes.
Five people, including two women, were arrested.
The Brotherhood of deposed president Mohamed Morsi has been depleted by a fierce security crackdown that has killed hundreds and arrested thousands of others.
Authorities brand the group, once Egypt's largest and most organised political group, a terrorist organisation.
They accuse it of links with militant fighters who have stepped up their attacks since Morsi's removal last summer.
Almost 500 police and soldiers have since been killed in shootings and bombings, according to a government tally.
Morsi, Egypt's first democratically elected president, was ousted by the army last July on the back of massive protests against his troubled one-year rule.
