CAIRO, June 25 (Xinhua) -- At least three people were injured Wednesday morning when two home-made bombs went off at two metro stations in the Egyptian capital of Cairo, the Interior Ministry source said.
The first explosion hit Shubra El-Kheyma station in northern Cairo during morning rush hours, causing slight injuries of three people. Meanwhile the second blast was caused by a sound bomb planted in a dust bin in Ghamra metro, the spokesperson of the interior ministry Abdel Fattah Othman said in a statement.
Othman denied some TV news about other two explosions in Kubry al Qupa and Ghamra stations.
However, head of Egypt's Ambulance Authority Ahmed al-Ansari told Xinhua that four people were wounded in three explosions in three metro stations, three at Shubra and one at Qupa station, the latter is very close to one of the presidential palaces.
Since the ouster of Islamist president Mohamed Morsi, a wave of militant attacks and explosions targeting security personnel and public institutions have risen mainly in the restive Sinai Peninsula. But recently, the attacks have crept into the capital and Delta cities.
Al-Qaida-inspired Ansar Bayt al-Maqdis claimed responsibility for most of the attacks, saying they were revenging for police crackdown on Morsi's supporters which left more than 1,000 dead.
The disposal team is combing other main metro stations for possible attacks, the report said, adding the metro resumed working after more than 15 minutes halt.
