Israeli military said it was carrying out airstrikes in the Gaza Strip on Sunday night, hours after Islamic Jihad fired barrages of rockets toward southern Israel.
A military spokesperson said the strikes targeted Islamic Jihad sites.
There were no immediate reports of casualties.
At least 23 rockets were fired on Sunday, with Islamic Jihad saying the fire was a retaliation for the killing of a senior member of the Islamist group.
Israeli Prime Minister Benjamin Netanyahu convened security consulting with Israel's top defense officials in the defense ministry in Tel Aviv to discuss possible retaliation to the rockets.
