Israel Defense Forces troops on Monday uncovered a third explosives laboratory in the West Bank city of Nablus, containing gas balloons, pipe bombs, explosives, computers and electrical equipment. The IDF's apparent targets in the Nablus operation were seven members of the Al Aqsa Martyrs' Brigades. Troops broke into transmissions of local TV and radio stations Sunday, broadcast the names of the men, and warned civilians against hiding the fugitives. Dozens of Al-Aqsa gunmen operate in Nablus, organized in small groups without a central authority. Residents have complained that some of the gunmen are terrorizing the city by settling personal scores in shooting attacks, acting as self-appointed vice squads, or engaging in blackmail.
