Palestinian Authority forces launched a large scale security crackdown in the Jenin district on Saturday. \"Security services are sending summons to all suspects who possibly partook in the shooting at the house of the late Jenin governor Qaddura Musa, and suspects involved in murder, blackmailing or other assaults,\" the commander of Jenin\'s security forces Radi Asida told Ma\'an. The governor of Jenin died from a heart attack on Wednesday, which officials say was brought on by an attack on his home by gunmen. The perpetrators of the attack have not been found and security services are working around the clock to bring them in, Commander Asida said. \"There will be detentions all around Jenin,\" he added. A number of members of the PA security forces have also been questioned on suspicion of involvement in different illicit activities, Asida said. The security campaign also aims to collect illegally possessed weapons in the Jenin district which could pose a threat to public security, he added. The northern West Bank city of Jenin became known as a center for Palestinian fighters during the second intifada, with many militant groups launching attacks on Israeli targets from the Jenin refugee camp.
