Israeli fighter jets struck Gaza after missile launches on Saturday, hours after U.S. President Joe Biden flew from Israel to Saudi Arabia as part of a Middle East trip aimed at deepening Israel's integration into the region, Reuters reported.

The Israeli military said it struck a rocket facility in central Gaza run by Hamas.

On Saturday, sirens went off twice in southern Israel, warning of an approaching rocket attack.

One rocket was intercepted and three shells fell in open spaces, the military said.

No group claimed responsibility for the launches.
