No injuries were reported, the army said.
A suspected weapons facility, two terror tunnels and other sites in southern and northern Gaza were hit, the Israeli army said.
The airstrikes were in response to mortar shells fired at soldiers operating in the Eshkol region earlier in the day, the army said,
"This morning Israeli soldiers came under terrorist fire while engaging in counter-terrorism activities," army spokesman Lt. Col. Peter Lerner said. The army will not tolerate attacks on soldiers and maintains the right to combat terrorists using the Gaza Strip as a springboard to attack Israeli soldiers and civilians, he said.
