Hardline Israeli Foreign Minister Avigdor Lieberman warned on Wednesday there would be “harsh and grave consequences” if the Palestinians persist with their plan to seek UN membership as a state.
Speaking shortly before a meeting with EU foreign policy chief Catherine Ashton, he did not elaborate on the possible consequences.
“The moment has not yet come to give details of what will happen,” he said.
In the past he has called for Israel to sever all relations with the administration of Palestinian president Mahmoud Abbas should it press on with its UN bid.
“What I can say with the greatest confidence is that from the moment they pass a unilateral decision there will be harsh and grave consequences,” Lieberman told an agricultural conference in southern Israel.
