Netivot, Southern Israel:The Israeli military said Hamas militants fired some 30 rockets from southern Gaza. It said its Iron Dome rocket-defence system intercepted several launches.
Earlier on Monday a rocket landed on a house in central Israel injuring seven people.
In response to the surprise rocket attack from the Palestinian territory the Israeli forces struck targets across the Gaza Strip, including the offices of Hamas' supreme leader.
The military also bolstered its troops and rocket-defence systems in anticipation of a new round of heavy fighting with the Islamic militant group.
