Four minor explosions have struck subway stations in the Egyptian capital Cairo, leaving two people injured and causing widespread panic among commuters.
The blasts, which were caused by home-made explosive devices, took place at four different stations in central and northern Cairo, in the Ghamra and Shubra el-Khemia areas.
Police quickly descended on the scene, sealing off stations and using sniffer dogs to search for more explosives.
No-one immediately claimed responsibility for the attacks – the first in the Egyptian capital since last month’s election of former army chief Abdel-Fattah el-Sissi as the country’s new president.
Mr el-Sissi led the military’s ousting of Islamist president Mohammed Morsi after millions demonstrated against him in the streets last July. Since Morsi’s demise, his supporters have staged near-daily protests demanding his return to power – demos which often descend into violence.
Security forces have killed hundreds and detained thousands of Morsi’s supporters and in return, Islamic militants have stepped up attacks against the military and police across Egypt.
An al-Qaida-inspired group based in Egypt’s Sinai Peninsula, Ansar Beit al-Maqdis, has claimed responsibility for most of the major attacks, including suicide bombings and attempted assassinations of top security officials.
However, other groups believed to be connected to Morsi’s supporters have claimed responsibility for smaller attacks, which have mainly targeted riot police heading to disperse protesters.
