A Kassam rocket fired by Gaza terrorists hit the Ashkelon Beach region on Sunday afternoon. No one was wounded and no damage was reported. The attack came hours after an explosive device was detonated near IDF troops patrolling the Gaza border fence. None of the soldiers were wounded in the Sunday morning incident and no damage was reported. The bomb attack came hours after the IAF struck two smuggling tunnels in the southern Gaza Strip. The army said air strike was in response to the Kassam rocket fired earlier Saturday night from the Strip. No one was wounded in the rocket attack and the Kassam, which hit the Sdot Negev region, did not cause any damage. The IDF said it would respond harshly to any attacks on Israel. According to the IDF, approximately 670 Kassam rockets, mortar shells and Grad missiles had been fired at Israel since the beginning of 2009. In related news, Gaza emergency services reported that an 18-year-old was electrocuted on Saturday afternoon in a smuggling tunnel under the Gaza-Egypt border. More than a dozen Palestinians have died in tunnel accidents this year.
