ISRAEL’S prime minister and defence chief will be called to testify in an investigation into a deadly raid on a Gaza aid flotilla, the leader of an Israeli commission of inquiry said in an opening statement yesterday.

The Israeli cabinet today gave final approval for an official investigation into the navy’s attack on a Gaza-bound aid flotilla two weeks ago, with the North's former first minister David Trimble one of two international participants.

Former Ulster Unionist Party leader David Trimble is to take part in an Israeli investigation into last month's raid on a Gaza-bound aid flotilla.
