A fifth battalion of Palestinian security forces, trained in Jordan under United States sponsorship, will return to the West Bank next week to beef up Palestinian Authority forces in cracking down on Hamas infrastructure in the territories. IDF sources confirmed that the battalion, which had been training for four months in Jordan, was scheduled to return to the West Bank next week ahead of Christmas. After the battalion returns, another battalion - consisting of several hundred security officers - will leave for training in Jordan in January. The sources said it was not yet known which city the battalion would deploy in. There are currently battalions deployed in Nablus, Jenin, Bethlehem and Hebron. The sources said that the Palestinian forces, trained by the Jordanians under the direction of US Gen. Keith Dayton, were doing a good job cracking down on Hamas infrastructure and restoring law and order in the West Bank.
