Palestinian forces operating out of the Gaza Strip fired at least one Grad missile into south-central Israel late Wednesday night.
The missile landed north of the coastal city of Ashdod, near the central town of Kiryat Malachi. It did not cause any injuries or damage.
Israel Radio reported that there may have been another two missiles fired at the same time, but the Israeli army has not confirmed that.
The attack marked the time missiles were fired from Gaza since Israel conducted a prisoner exchange with the region's Hamas rulers last week. In that deal, Israel secured the releaes of abducted soldier Gilad Shalit by freeing 1,027 jailed Palestinian terrorists. Hamas has vowed to lure and abduct more Israeli soldiers so that it can trade them for the rest of the Palestinian terrorists sitting in Israeli jails.
