Israel later fired three surface-to-surface missiles from an army base east of Gaza City, hitting a car, killing one Hamas militant and wounding 22 other people, a Palestinian public security spokesman said.
An Israel Defense Forces spokesman said Palestinians also fired two Qassam rockets from the Gaza Strip into Israel. One landed in an open area and was not found. The second hit the town of Sderot, and five people were treated for shellshock.
Earlier Friday in the West Bank village of Dura, near Hebron, Israeli troops demolished the home of a militant who carried out several shooting attacks.
They also demolished the Hebron home of the suicide bomber who carried out Wednesday's deadly bus bombing in Jerusalem. The attacker, a Palestinian dressed as an ultra-Orthodox Jew, blew himself up on a bus in the capital.
The death toll from the bombing rose to 17 Thursday when a 70-year-old died of injuries sustained in Wednesday's attack.
Twenty-seven of the more than 100 wounded remained hospitalized Thursday, six of them in serious condition.
