Israeli airstrikes hit targets in Gaza in response to a Kassam rocket fired into the Negev.
Two smuggling tunnels and a weapons factory in southern Gaza were hit in the Air Force raid overnight Wednesday, according to the Israel Defense Forces.
About 15 rockets and mortar shells have been fired from Gaza at Israel in the past month, the IDF said.
No damage or injury was reported from the Kassam, which was fired early Wednesday morning and caused the Color Red siren to sound in the area.
On Wednesday afternoon, an explosive device was detonated against Israeli forces patrolling the border with the central Gaza Strip.
More than 250 rockets and mortar shells have been fired at Israel since the end of Operation Cast Lead in January; more than 750 have hit Israel in 2009.
