An Egyptian policeman and seven suspected militants were killed on Tuesday in an exchange of gunfire, the ministry of interior said in a statement late on Tuesday. It said three other policemen had also been wounded. The exchange took place in the al-Amiyira district, the public prosecutor said in a statement. The ministry received information “that there is a terrorist cell, whose elements embrace Takfiri ideology, using several areas as a shelter in eastern and southern Cairo as a starting point to carry out terrorist operations,” the statement said. Egypt uses the term takfiri to refer to Islamist militants who often accuse their victims of being infidels. Two private television stations broadcast what they called footage of the shooting, which Reuters was not immediately able to verify, and asked residents to stay indoors. Weapons and ammunition were found with the suspects, the ministry said. The public prosecutor said a team of investigators has been dispatched to the scene of the attack.
