A senior police officer was killed when Egyptian security forces stormed a village outside Cairo Thursday in the latest crackdown on militants, while news of unexploded bombs on the tracks briefly halted Cairo's metro.
  
Military and police vehicles surrounded Kerdassah in the shadow of landmark pyramids after dawn, as police Special Forces were deployed to confront "terrorists" in the village, the interior ministry said.
  
Giza security chief Nabil Farrag was killed in clashes while 32 people were arrested in the operation.
  
Authorities slapped a daytime curfew on the village as they went door to door in search of 140 wanted men, including those behind a "massacre" in Kerdassah in which 11 policemen were killed on August 14.
  
"Security forces are pursuing their campaign in Kerdassah and will not stop until it clears (the village) of all terrorist and criminal elements," interior ministry spokesman Hani Abdel Latif told reporters.
 
Thursday's operation comes days after a similar raid on the central Egyptian town of Delga in the Minya province, which was held by Islamists for more than a month.
