The constant sounds of boom one after the other resonate across Ashkelon, a town in southern Israel. These are the sounds of retaliation by Israel which was caught by surprise on Saturday when a barrage of rockets rained down. Scores of Israelis and foreign nationals have died in the attacks launched by the Hamas group. The attacks are still on and several terrorists are believed to be present in towns in southern Israel. Sounds of boom and sirens ring through cities as Israel fights back the terror strikes.
