An Israeli air raid in Gaza City has killed at least three people.
Another two people were injured in the attack on a car, according to Palestinian medical officials.
An Israeli aircraft hit the Zeitoun neighbourhood of the city on Thursday, sources said.
One of the people killed was identified as a member of the armed wing of the Islamic Jihad movement.
A spokeswoman for the Israeli army confirmed the attack saying it was aimed at a group that "was responsible for firing rockets against Israel".
The car was obliterated by the blast, and rescue workers extracted a dismembered body. Hamas police officers kept people away from the car.
Thursday's deaths brought the number of people killed in Israeli-Palestinian violence since 2000 to 5,976, the vast majority of them Palestinians, according to a count by the AFP news agency.
