REUTERS - A series of small explosions wounded at least four people at two Cairo metro stations during the morning rush hour on Wednesday, security sources said, highlighting some of the challenges faced by newly elected President Abdel Fattah al-Sissi.
Another explosion detonated by a car outside a court in the northern Cairo district of Heliopolis wounded one, Major General Alaa Abdel Zaher, the head of Cairo's bomb disposal unit, told Reuters.
Explosions hit Ghamra metro station in central Cairo and Shubra El-Kheyma, a northern district of Greater Cairo, according to state television and security sources.
Three people were wounded at Shubra, according to security sources, and one person at Ghamra, according to the television report.
An interior ministry official told a privately owned television channel that one person was wounded carrying a home-made bomb to Shubra El-Kheyma station. He added the Ghamra incident was caused by an explosion in a rubbish bin.
Egypt has been hit by a wave of violence, mainly attacks by Islamist militants based in the Sinai peninsula on security forces, since the army ousted Islamist President Mohamed Morsi in July following mass protests against him. Former army chief Sissi, who deposed Morsi, was sworn in as president after winning elections last month.
His supporters see him as a strongman who can save Egypt from chaos after more than three years of political and economic turmoil, following a 2011 revolt that swept veteran autocrat Hosni Mubarak from power.
