Foreign Affairs and Defense Committee Chairman Ze'ev Elkin said on Sunday that the committee would investigate the "difficult questions" relating to the Gaza Operation. "This is precisely the role of the committee, to question everyone who was there. The issue of the tunnels is only one element to probe, and I'm not sure it is even the most central subject for investigation," he told Army Radio. Elkin said that it was not the appropriate time to sound the questions on the war in public because the fighting was still going on."We are still fighting. Whoever thinks that this operation is over needs to ask Hamas leader Khaled Mashaal," he told Army Radio.
