Israel offered to help moderate Arab nations threatened by a lightning offensive by Islamic militants in Iraq, as the country's top diplomat met with US Secretary of State John Kerry on Thursday. Israeli Foreign Minister Avigdor Lieberman told Kerry at a meeting in Paris that "the extremists currently operating in Iraq will try to challenge the stability in the entire Gulf region, first of all in Kuwait," a statement from the Israeli minister's ****** said. "Israel could provide effective and reliable assistance to moderate Arab states who are dealing with extremists," it added, without going into specific details. Just a few days after visiting Iraq, Kerry said it was "important that countries in the region stand together against the threat," according to a senior US official.
