There were no reports of injuries from the airstrikes in southern Gaza Strip, AP reported.
The Israeli military claimed the sites belonged to Hamas and included weapons manufacturing and intelligence-gathering facilities.
Tel Aviv says the attacks were in retaliation for Hamas' alleged launch of "incendiary balloons" directed toward the occupied territories.
In trying to bolster the Egyptian and UN-mediated truce, Hamas halted the regular weekly protests along the Gaza-Israel fence last month.
Earlier this week, Israeli planes sprayed toxic chemical substances and dangerous pesticides on farmlands near the Gaza Strip in the latest case of the Tel Aviv regime's acts of aggression against the besieged Palestinian coastal enclave.
