CAMDEN, N.J. — A federal judge has ruled against three immigrant brothers seeking to overturn their life sentences for plotting to kill U.S. soldiers at Fort Dix, New Jersey.

U.S. District Judge Robert Kugler ruled that he didn’t buy the arguments from Dritan (DRY’-tahn), Eljvir (EL’-veer) and Shain Duka (DOO’-ka) that they were wrongly convicted in 2008 because their lawyers kept them from testifying.

Kugler ruled Friday that he found testimony from their defense attorneys at a January hearing more credible. His decision was filed Wednesday.

The Albanian-born brothers were convicted with two others of plotting an attack at military sites at Fort Dix and elsewhere. Supporters believe the FBI entrapped them and exaggerated the case, but the Dukas have exhausted their appeals.
