According to the air force, a Hamas weapons factory and a tunnel used by fighters of the group were the targets of the bombings.
Palestinian authorities confirmed the airstrikes but said the targets were a training camp and an uninhabited area near Rafah. There would have been no casualties.
In August, at least 49 people in the Gaza Strip were killed during three days of fighting between Israel and Palestinian militants in the area. Egypt then brokered a ceasefire.
