The United States and Canada have welcomed Israel's move to set up an independent public commission into last month's deadly raids on a flotilla of aid ships that killed nine people. Though the US has welcomed the move, it said the public commission must carry out its work promptly. Meanwhile, Canada said it supports an impartial, credible and transparent investigation into what happened on board the ships. <br/><br/>The Israeli government is expected to vote on the inquiry today, although it is yet to announce any terms of reference. Israel has repeatedly rejected calls for an international panel to investigate the raids on May 31 and has appointed retired Supreme Court judge Yaakov Tirkel to head the inquiry. <br/><br/>However, it has agreed to include two foreign observers in its own independent public commission, Irish Nobel Peace Prize winner David Trimble and a former Canadian judge advocate general.
