A total of four Palestinians were killed on Thursday in Israeli air strikes on Gaza, bringing the total number of victims to six, since Wednesday.
Medics uncovered a body of a 65-year-old man who was believed to be the victim of tank shelling.
Two people died when an Islamic Jihad sports facility was targeted in the northern Gaza strip, while one man died in an air raid on underground smuggling tunnels near the Egyptian border, in the south of the strip.
In addition, about 20 were wounded, and some remain in critical condition.
Meanwhile, Gaza residents attended the funeral of an Islamic Jihad militant who died in overnight raids.
The attacks interrupted a ceasefire established on Monday between Israeli and Palestinian parties in Gaza after five continuous days of border clashes.
