Emergency sirens sounded in several cities in southern Israel Sunday night, as a rocket was fired from the Gaza Strip in the direction of Ashkelon, setting off the Code Red alert in the Hof Ashkelon Regional Council.

The rocket landed in open Palestinian territory close to the security fence with Israel, according to Israel Radio. No damage or injury was reported.

On Saturday, a rocket fired from Gaza apparently exploded in open areas in the Sha’ar Hanegev region, causing neither injury nor damage.

According to the IDF’s official figures, 108 rockets have been fired at Israel from the Strip since the beginning of 2014.

Later Saturday, three Palestinian men were arrested by IDF soldiers after they crossed the border from the Gaza Strip into Israel.

It was not immediately clear what their motive was, and they were transferred to security forces for interrogation, Army Radio reported.
