The IAF struck a weapons storehouse in Rafiah in the southern Gaza Strip on Monday night.
The army reported that the storehouse contained Kassam rockets and explosive devices, and that residents had been warned to leave the area so as to avoid civilian casualties.
No injuries were reported in the attack.
Earlier, the IAF struck another arms storehouse in the Jabalya refugee camp in northern Gaza. Two people were lightly wounded.
