Palestinian terror groups announced on Monday night that they had successfully launched a Kassam rocket from Jenin in northern Samaria toward the community of Ram-On in northern Israel. According to the joint announcement put out by the Aksa Martyrs Brigades of the Fatah and the Jerusalem Brigades of the Islamic Jihad, the rocket landed in the Palestinian autonomous area. IDF sources from Central Command rejected the Palestinian report, claiming that not only had the rocket not landed in Palestinian autonomous territory, it had never even been fired. An IDF source further added that the Palestinians in Jenin did not have the ability to develop, manufacture or launch rockets at Israel. IDF units, he said, were operating around the clock inside Jenin and other West Bank cities in an effort to destroy rocket-production infrastructure and to thwart such attacks. In the past year, the IDF has arrested Palestinian terrorists from the Gaza Strip who have tried to infiltrate Israel in order to reach the West Bank to help establish a Kassam-production infrastructure there. The IDF has also thwarted attempted rocket and mortar attacks on Israeli cities from the West Bank.
