JERUSALEM –  Israeli officials have denied allegations in a U.N. report that international activists detained during a deadly raid of a Gaza-bound flotilla were abused.

In testimony to an Israeli investigative committee in Jerusalem on Monday, Interior Ministry official Yossi Edelstein, who was in charge of processing detainees, said everyone was treated "with restraint and respect." He also said he had received no formal complaints of mistreatment.

The U.N. report accused Israel of "extreme and unprovoked violence" against detainees.

Israel detained hundreds of activists after clashes with passengers on board one of the boats in the May assault on the flotilla. Nine activists died in the violence. All foreign detainees were deported within several days.
