Gaza terrorists fired a rocket into downtown Netivot around 21:30 (GMT+2) on Tuesday evening.
Magen David Adom reported that one person was lightly injured after being hit in the hand by flying glass. 11 people suffered shock.
The attack came just hours after a pair of rockets slammed into the Ashkelon beaches. No physical injuries were reported in that attack.
At least seven rockets were fired into Israel earlier in the day despite a cease-fire brokered between Israel and Gaza's terror factions by Egypt.
The attacks come as residents in Israel's south are prepare to resume their normal routines on Wednesday with a return to work and school.
Islamic Jihad, a terror faction heavily involved in recent rocket attacks on Israeli communities, has said it will not honor any truce that does not include Israel's promise to halt targeted killings of terror leaders.
During four days of hostilities terror groups fired more than 200 rockets at Israeli civilians, while the IAF responded by targeting the cells firing the rockets – killing 27 Gazans, of whom 25 were terrorists.
The IDF laid the blame for civilian casualties at the door of the terror gangs, noting they were firing rockets from deep within densley populated civilian areas and using civilians as human shields.
IDF chief of staff Benny Gantz, who previously called for a major ground incursion into Gaza to root out the terror infrastructure there, promised "Quiet for quiet and fire against fire,” after the cease-fire was declared.
