Israeli fighter jets bombed three sites affiliated with the Ezzedine al-Qassam Brigades, Hamas's armed wing, at dawn Thursday in the blockaded Gaza Strip.
Eyewitnesses told Anadolu Agency that Israeli warplanes had struck three separate positions inside the strip: two in the south and one in the north.
According to Palestinian medical sources, the strikes did not result in any casualties.
Earlier Thursday, the Israeli army claimed that a rocket was fired from Gaza into Israeli territory.
In a tweet, Israeli army spokesman Avichay Adraee said that Israel's Iron Dome air-defense system had responded to the rocket launch.
He did not say, however, whether or not the rocket was successfully intercepted.
The latest escalations come amid a fresh round of shuttle diplomacy by Egyptian officials between Gaza and Ramallah (the Palestinian government's administrative capital) aimed at hammering out a Hamas-Israel truce and promoting Hamas-Fatah reconciliation.
