Israel is expected to broaden the powers of an internal inquiry into the botched raid on a Gaza-bound flotilla in May in the wake of a barrage of claims that its investigation lacks any credibility. Benjamin Netanyahu, the Israeli Prime Minister, appeared to cave in to domestic pressure after the committee was mocked in the Israeli media as a whitewash designed to defend the assault on 31 May that resulted in the death of nine Turkish nationals. A photograph of one 93-year-old panellist in his pyjamas looking at documents drew particular derision.
