Palestinians in Gaza fired a rocket early Sunday morning at the Eshkol region in southern Israel.
The rocket fell in a field and caused neither casualties nor damage.
IDF troops were searching for the impact site.
It was the first rocket attack in a week.
Over 100 projectiles fired by terrorists in the Gaza Strip, ruled by the Islamist movement Hamas, have crashed into Israel since the start of 2014, according to military data.
