Two Kassam rockets landed in an open field north of Sderot Wednesday morning, raising the total number of rockets fired Wednesday to five. Two rockets also landed south of Ashkelon. No casualties or damage were reported in the attacks. Earlier Wednesday, however, unspecified damage was caused at the site of the first missile's impact, which was near one of the Jewish communities that border the northern Gaza Strip, according to an Army Radio report. Islamic Jihad claimed responsibility for the attacks. Earlier in the day undercover Border Policemen killed three Islamic Jihad operatives in the West Bank town of Jenin. Following the operation a spokesman for Islamic Jihad in the Gaza Strip, Abu Ahmad, warned Israel, "This new crime will not pass without tough punishment. "Their blood will be the fuel of our holy battle. And our reaction is coming soon."
