Israeli Foreign Minister <a gi-track='captionPersonalityLinkClicked' href=/galleries/search?phrase=Avigdor+Lieberman&family=editorial&specificpeople=652650 ng-click='$event.stopPropagation()'>Avigdor Lieberman</a> briefs the media during a press conference on May 31, 2010 in Jerusalem, Israel. The killing of at least nine pro-Palestinian activists in an Israeli naval raid earlier in the day on an aid flotilla bound for the blockaded Gaza Strip has generated international condemnation. In response Lieberman accused the flotilla of being manned by terrorist supporters and that Israel had no intention of allowing an any attack on the sovereignty of Israel. Israeli Prime Minister Benjamin Netanyahu has returned to Israel, cancelling a meeting scheduled for tomorrow with President Barack Obama which was hoped might address tensions in US and Israeli relations and regain momentum in the peace process.
